Question

The spring of a toy car is wound by pushing the car

backward with an average force of 15 newtons through
a distance of 0.50 meter. How much elastic potential
energy is stored in the car's spring during this process?

Answer 1

7.5 Joules is the amount of elastic potential energy stored in the car's spring during this process.

w=Fd

w=(15)(0.5)

w = 7.5
