Question1
A 150, 30.0-cm-diameter turntable rotates on frictionless bearings at 61.0. A 17.0 block sits at the center of turntable. A compressed spring shoots the block completely outward along a frictionless groove in the surface of turntable. What is the turntable's angular speed as the block reaches the outer edge?
Question2
An object in space is initially stationary relative to the Earth. Then, a force begins acting on the object, starting with a force of 0 N, and increase at a uniform rate until the magnitude of the force is 48 N after force has acted for 35 s the body has a mass of 15 kg. What is speed of the object at 35 s?
