A horse pulls a carriage by applying 450 N of force. Find the traveled distance if the horse did 89 kJ of work.

distance = 197.8  m

Explanation:

Use the formula for work as the force times the distance the force was acting on the object.

W = F * d

89000 J = 450 N * d

d = 89000/450 m

d = 197.8  m

Mary concludes that the foam rubber balls’ acceleration during the collision was THE SAME AS the steel balls’ acceleration. She concludes that the collision between the foam rubber balls is an ELASTIC collision.

The masses of the two objects are the same therefore its acceleration would also become the same. It is an elastic collision because little or less friction occurred in the situation creating kinetic energy.
