Kitty is pushing her shopping trolley along the ground. She applies a constant force to move the trolley 4 m horizontally. If she does 32 J of work, calculate how much force she is applying.

the constant force applied by Kitty is 8 N.

Explanation:

Given;

work done by Kitty, W = 32 J

distance moved by Kitty's trolley, d = 4 m

Let the constant force applied by Kitty = F

The work done by Kitty is calculated as follows;

W = F x d

F = W / d

F = 32 / 4

F = 8 N.

Therefore, the constant force applied by Kitty is 8 N.

this means that the temperature of both substances will be equal
