A chef pushes a 10kg pastry cart from rest a distance of 5 meters with a constant horizontal force of 10N. Assuming a frictionless surface, determine the cart’s change in KE and its final velocity.

What would be the strength of earth's gravitational field at a point where an 80.0 kg astronaut would experience a 80% reduction in weight
