Question

A 100-N force has a horizontal component of 80 N and a vertical component of 60 N. The force is applied to a cart on a level frictionless floor. The cart starts from rest and moves 2.0 m horizontally along the floor due to this force. What is the cart's final kinetic energy ?

Answer 1

$ΔK = W = F_xx = 80 \times 2 = 160 \;Joules$
