Question

A hockey player uses her hockey stick to exert a force of 6.81 N on a stationary hockey puck. The hockey puck has a mass of 165 g. What is the acceleration of the hockey puck?

a. 0.13 m/s2

b. 11.3 m/s2

c. 21.3 m/s2

d. 31.3 m/s2

e. 41.3 m/s2

Answer 1

Answer:

41.3 m/s^2 option (e)

Explanation:

force, F = 6.81 N

mass, m = 165 g = 0.165 kg

Let a be the acceleration of the puck.

Use newtons' second law

Force = mass x acceleration

6.81 = 0.165 x a

a = 41.27 m/s^2

a = 41.3 m/s^2

Thus, the acceleration of the puck is 41.3 m/s^2.
