A steel washer is suspended inside an empty shipping crate from a light string attached to the top of the crate. The crate slides down a long ramp that is inclined at an angle of 32? above the horizontal. The crate has mass 243kg . You are sitting inside the crate (with a flashlight); your mass is 63kg . As the crate is sliding down the ramp, you find the washer is at rest with respect to the crate when the string makes an angle of 72?with the top of the crate. What is the coefficient of kinetic friction between the ramp and the crate?
A skier of mass 68.4 kg glides down a hill of slope 26.5 degree at constant speed. If she travels a distance 35.0m down the hill, what is (a) the work done by friction and (b) the coefficient of friction between her skis and the slope?
You're carrying a 4.0-m-long, 25 poles to a construction site when you choose to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35 from its tip. How much force should you exert to keep pole motionles..
A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 81.0 m/s at ground level. The engines then fire.
A block slides down an inclined plane, starting from rest and being pushed with a constant acceleration of 4.60 m/s2 over the distance of 20.80 cm. It then decelerates at the constant rate of 1.03m/s2 (because of friction), until it again comes to..
What are the max and min values of the instantaneous power?
An electric scooter has a battery capable of supplying 140 Wh of energy. If friction forces and other losses account for 60.0 percent of the energy usage, what altitude change can a rider achieve when driving in hilly terrain, if the rider and scoote..
