a player pushes a 250-g hockey puck over frictionless ice witha constant force, causing it to accelerate at 24 m/s2over a distance of 50.0 cm. A. Find the work done by the hockey player on the puck? B. What is the change in the kinetic energy of the puck? a player pushes a 250-g hockey puck over frictionless ice witha constant force, causing it to accelerate at 24 m/s2over a distance of 50.0 cm.

Explanation / Answer
force on te puck F = ma m = mass of the puck a = puck accleration distance moved be S work done W = F*S change in kinetic energy KE = W .
