- A golf ball is fired straight up into the air from ground level. It reaches a maximum height at ℎ = 504 meters. Calculate the initial speed of the golf ball in meters per second.During the siege of Constantinople that led to its conquest by the Ottomans in 1453, the Hungarian engineer Orban built a set of bombards (primitive cannon) to throw enormous stones at the city to breach its walls. The largest of these could throw a 300 kg stone a distance x = 2 km. Assume that the stone was launched at an angle of 0 = 45 degrees above the horizontal; in the absence of air resistance, this gives the largest range. a) What speed did the stone have to be launched at to achieve this range? b) How long was the ball in the air? c) How fast was the ball traveling at the apex of its flight?a catapult launches a test rocket upward from well giving it a speed of 50 m/s at ground level. the engines then fire so that the rocket accelerated at 5 m/s^2 until it reaches an altitude of 750 m at which point it gos into free fall. what is the maximum altitde of the rocket?
- Sofia is playing a game with her friend, Kara, where she throwsM&M candies at Kara and Kara catches the M&M’s in hermouth. They begin standing 1.75 meters apart from eachother. Sofia throws the M&M at an angle of 60 degrees abovethe horizontal with a speed of 4.13 m/s. Kara’s mouth is145 cm above the ground when she catches the M&M. Whatheight above the ground did the M&M leave Sofia’s hand?Hint: Remember, even though the motion in the horizontaldirection is independent of the motion in the vertical direc-tion, they share the same time.An Olympic diver is on a diving platform 5.20 m above the water. To start her dive, she runs off of the platform with a speed of 1.3 m/s in the horizontal direction.

Express the initial velocity as a linear combination of its unit vector components. Vo - ( mis) 7 + m/s) ? At the maximum height, the speed of the cannon ball is v= m/s and the magnitude of its acceleration is a- m/s?. The time needed to reach maximum height is t- S. The maximum height reached by the cannon ball is H= m.

INGLÉS ESPAÑOL FRANCÉS A projectile is launched horizontally with a speed of 125 m/ s, at a height of 68 m above sea level. Skip the air resistance and calculate the speed of the projectile when it hits the sea Enviar comentario d ENG 6:09 PM 10 ofProfessional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. a) Calculate the velocity of the ball just after it is struck b) What is the 0.0450 kg ball's change in momentum?
