- Olympus Mons on Mars is the largest volcano in the solar system, at a height of 25 km and with a radius of 312 km. If you are standing on the summit, with what Initial velocity would you have to fire a projectile from a cannon horizontally to clear the volcano and land on the surface of Mars? Note that Mars has an acceleration of gravity of 3.7m/s2 .arrow_forwardA guy is standing on a relatively flat surface (h = 0 m). A pesky drone is flying overhead at a height of 120 m above the ground and with a velocity of 15 m/s. The guy gets annoyed and fires an arrow with an initial velocity of 100 m/s the instant the horizontal distance between him and the drone is 5 m. At what angle must he fire the arrow in order to hit the drone? Take the guy's height to be 1.8 m. Just to clarify, would shooting an arrow follow the same rules as a regular projectile motion problem? Thanks.arrow_forwardAn archer aims at a target a horizontal distance 55 m away and 5.0 m above the ground. The archer launches her arrow from of height of 1.5 m off the ground, and the arrow hits the target. The arrow is completely horizontal after sticking to the target (i.e., the arrow was traveling horizontally just before hitting the target). What was the initial speed of the arrow?arrow_forward
- At a top of a building, a projectile is launched with an initial velocity of 25.0m/s at an angle of 30° above the horizontal. It takes the projectile t = 3.96s from launch to hit the ground. What is the velocity of the projectile as it hits the ground? (Magnitude + Direction)arrow_forwardQuestions 1 through 3 pertain to the situation described below: An archer wants to launch an arrow from a bow to clear a treetop that is 35.0 m vertically above, and 97.0 m horizontally away from, the launching location. Assume that the launching speed is 57.0 m/s and the launching angle is 0 above the horizontal. (1) How much does the arrow clear the treetop if 0 = 30.0°? (A) 3.6 m; (B) 3.1 m; (C) 2.6 m; (D) 2.1 m; (E) 1.6 m. (2) What is the maximum horizontal range of the arrow if 0 can vary? (A) 212 m; (B) 242 m; (C) 272 m; (D) 302 m; (E) 332 m. (3) What is the range of 0 for the arrow to clear the treetop? (A) 29.9-86.0°; (B) 28.9–81.0°; (C) 27.9–76.0°; (D) 26.9–71.0°; (E) 25.9–66.0°.arrow_forwardIn the figure, a ball is launched with a velocity of magnitude 7.00 m/s, at an angle of 41.0° to the horizontal. The launch point is at the base of a ramp of horizontal length d1 = 6.00 m and height d2 = 3.60 m. A plateau is located at the top of the ramp. Does the ball land on the ramp or the plateau? When it lands, what are the magnitude and angle of its displacement from the launch point?arrow_forward
- Consider a projectile being launched with an initial speed of 58 m/s at a variety of initial angles. What is the range, in meters, of the projectile if it is launched at an angle of θ1 = 78.3°?arrow_forwardA cannon is fired over level ground at an angle of 30 degrees to the horizontal. The initial velocity at this angle is 80 m/s, but this velocity may be separated into a vertical velocity component of 40 m/s and a horizontal velocity component of 69.3 m/s. How far does the cannonball travel horizontally?arrow_forwardSolve the problem by showing all complete solutions and illustration. An arrow is shot from a height of 1.5 m toward a cliff of height H. It is shot with a velocity of 30 m/s at an angle of 60° above the horizontal. It lands on the top edge of the cliff 4.0 s later. (a) What is the height of the cliff? (b) What is the maximum height reached by the arrow along its trajectory? (c) What is the arrow’s impact speed just before hitting the cliff?arrow_forward
- Spitting cobras can defend themselves by squeezing muscles around their venom glands to squirt venom at an attacker. Suppose a spitting cobra rears up to a height of 0.440 m above the ground and launches venom at 3.70 m/s, directed 39.0° above the horizon. Neglecting air resistance, find the horizontal distance (in m) traveled by the venom before it hits the groundarrow_forwardA helicopter is flying horizontally with a speed of 67.3 m/s over a hill that slopes upward with a 5% grade (that is, the "rise" is 5% of the "run"). The helicopter's velocity is horizontal with a magnitude of 67.3 m/s and can be resolved into components parallel and perpendicular to the hill. Calculate the magnitude of the perpendicular component.arrow_forwardDuring a baseball game the ball is hit at home base 1 meter above ground level with a bat. After having traveled a horizontal distance of 30 m, it is 20 m above ground level. An outfielder runs to meet the ball and catches it as he dives, just 10 cm from the ground. The outfielder is 80 m away from home base when he catches the ball. Assuming the path of the ball is approximately parabolic, what is the greatest height the ball reaches?arrow_forward
