A hockey puck with a mass of 0.16 kg is sitting at rest on a frozen pond. Suddenly, the wind begins to blow, accelerating the puck across the ice at 625 m/s2. If friction is ignored, the force of the wind can be calculated to be _______.

Answer:

100 N

Explanation:

According to Newton's Second Law, the net force acting on an object equals the object's mass times its acceleration. Ignoring friction, the force of the wind is equal to the net force acting on the puck. Thus, the force of the wind can be calculated as follows:

F = ma

F = (0.16 kg)(625 m/s2)

F = 100 N
