You push a 1.5 kg ball across a desk and it accelerates at a rate of 0.5m/s2 for 5 m. How much work was done?

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
