Question

A Stegosaurus hits' a wall with a force of

60 N and has a mass of 32kg. What
was the acceleration of the dino?
1920

Answer 1

Answer: a= -1.9 m/s²

Explanation: F = ma and a = F / m = 60 N / 32 kg = 1.875 m/s²

Because of law of action and reaction, wall applies same force to dino

In opposite direction and Dino is decelerating. Thus sign Is negative.
