1. A shopper is pushing a 14.8-kilogramshopping cart, initially at rest, with a 15.0 Newton force that is parallel to the floor. The force of friction on the cart is 5.0 nektons.
Utilize the work-kinetic energy theorem to decide the speed of the cart after the cart has been pushed for 5.0 meters.
2. A 65.0-kilogram child starts from rest from the top of a frictionless slide that is 5.0 meters tall. The bottom of the slide is 20.2 centimetres above the ground.
What is the child's speed at the bottom of the slide?
