On an ice rink, Manuel pushes off the wall with 540 N of force. If his mass is 72.0kg, what is his

acceleration on the skates (assume that the friction is essentially 0).

Answer: 7.5m/s2

Explanation:

Force applied = 540 N of force.

mass = 72.0kg

acceleration on the skates = ?

Recall that Force is the product of mass of an object and the acceleration by which it moves.

Force = mass x acceleration

540N = 72.0kg x acceleration

Acceleration = 540N/72.0kg

= 7.5m/s2
