Question

A dog has a mass of 20 kg. If the dog is pushed across the ice with a force of 40 N, what is its acceleration?

Answer 1

The acceleration is 2 m/s2.

Step-by-step explanation:

We calculate the acceleration (a), with the data of mass (m) and force (F), through the formula:

F = m x a ---> a= F/m

a = 40 N/20 kg 1N= 1 kg x m/s2

a= 40 kgx m/s2/ 20 kg

a= 2 m/s2
