A cart is being pulled up a ramp at an angle of 20 deg, with a net force of 1000 N. The rope used to pull the car makes an angle of 30 deg with the cart's direction of motion. Calculate the work done by the force (or in other words energy required to pull the cart), if the distance travelled is 3 m (along the ramp).
