An athlete is running at a constant velocity with a javelin held in his right hand. the force he is applying on the javelin as he carries it is 5.0 newtons. if he covers a distance of 10 meters, what work has he done on the javelin?

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

A51 kg woman skis down a hill and her kinetic energy is 9.96e4 j. what is her speed?

Aplayer uses a hockey stick to push a puck at a constant velocity across the ice. the weight of the puck is 170 n. the coefficient of friction is 0.0600. with what force must the player push the puck so that his force just equals the frictional force? 28.3 n 0.999 n 0.102 n 0.0104 n
