- A 75.0-g arrow, fired at a speed of 110 m/s to the left, impacts a tree, which it penetrates to a depth of 12.5 cm before coming to a stop. Assuming the force of friction exerted by the tree is constant, what are the magnitude and direction of the friction force acting on the arrow?arrow_forwardYou push an object, initially at rest, across a frictionless floor with a constant force for a time interval t, resulting in a final speed of v for the object. You then repeat the experiment, but with a force that is twice as large. What time interval is now required to reach the same final speed v? (a) 4 t (b) 2 t (c) t (d) t/2 (e) t/4arrow_forwardA 200-g hockey puck is launched up a ramp that is inclined at a 30° angle above the horizontal. The coefficients of static and kinetic friction between the puck and the ramp are µs = 0.40 and µk = 0.30, respectively, and the puck's initial velocity at the base is 3.8 m/s parallel to the sloping surface of the ramp. What speed does the puck have when it slides back down to its starting point?arrow_forward
- A 200-g hockey puck is launched at an initial speed of 16 m/s up a metal ramp that is inclined at a 30° angle. The coefficients of static and kinetic friction between the hockey puck and the metal ramp are μs = 0.40 and μk = 0.30, respectively. What vertical height does the puck reach above itsstarting point?arrow_forwardA 5.00 kg box sits at rest at the bottom of a ramp that is 8.00 m long and is inclined at 30 degrees above the horizontal. The coefficent of kinetic friction between the box and the surface is 0.40, and coefficent of static friction is 0.43. What constant force F, applied parallel to the surface of the ramp, is required to push the box to the top of the ramp in a time of 6.00 seconds?arrow_forwardSuppose you are at a bowling alley, where a machine uses a constant force and pushes balls up a ramp one meter in length. The balls are sliding -- not rolling -- along the incline, and they end up half a meter above the base of the ramp. Ignore friction. Approximately how much force does the machine put on a 5 kg bowling ball? 1.0 m H 0.5 m 200 N 50 N 25 N O 5N Impossible to determinearrow_forward
- A 15-pound box sits at rest on a horizontal surface, and there is friction between the box and the surface. One side of the surface is raised slowly to create a ramp. The friction force f opposes the direction of motion and is proportional to the normal force F exerted by the surface on the box. The proportionality constant is called the coefficient of friction, u. When the angle of the ramp. 0, reaches 25°, the box begins to slide. Find the value of u 15 pounds The value of u is (Do not round until the final answer. Then round to two decimal places as needed.)arrow_forwardKarev is lowering two boxes, one on top of the other, down the ramp, as shown in the figure, by pulling on a rope parallel to the surface of the ramp. Both boxes move together at a constant speed of 15 cm/s. The coefficient of kinetic friction between the ramp and the lower box is 0.444, and the coefficient of static friction between the two boxes is 0.800. (a) What force do you need to exert to accomplish this?arrow_forwardAt Ted's request, Bill pushes the pizza box across the granite countertop towards Ted. When the box leaves Bill's hand it is sliding at 2.60 m/s. The box comes to rest over a distance of 110 cm. What is the coefficient of kinetic friction, uk, between the pizza box and the countertop? (Ignore air drag.)arrow_forward

It covered a distance of 10 meters. What is the amount of force (Newton) exerted by John and Peter if the coefficient of kinetic friction is 0.100 ?arrow_forwardA 10.2-kg box is sliding across a horizontal floor. It has an initial speed of 1.25m / s and the only force acting on it is kinetic friction with magnitude f(k)= 2.35N .Determine the distance the box will travel before coming to restarrow_forward
