If the man DECREASES the force of his push on the cart, the cart slows down.

Force acting on body

The force applied to an object is determined by applying Newton's second law of motion.

F = ma

where;

  • m is mass of the body
  • a is acceleration of the body

a = Δv/t

F = (mΔv)/t

mΔv = Ft

Δv = Ft/m

From the equation above, when the applied force decreases, the change in velocity decreases.

Thus, if the man DECREASES the force of his push on the cart, the cart slows down.
