A book is given a sudden push to make it slide along a desktop. If the initial speed of the slide is doubled, by what factor is the distance that the book slides changed? A 20 kg cart is moving at 2.0 m/s when a 5.0 N force is applied for a distance of 6.0 m in the direction the car is moving. What is the kinetic energy of the cart at the end of the 6.0 m? A 0.145 kg baseball is thrown from a platform above the ground at a 10 m/s. The ball is moving 15 m/s when it strikes the ground. From what height above the ground was the ball thrown?

Well let see, we don't have any information about the initial distance we have to use our logic assuming that the distance moves from 1 to 2 m with initial speed , it means that the distance factor is 2 Since the initial speed has doubled, it would be very likely that the factor of the distance is MORE THAN 2 . Find the answer that either got 3 or 4 distance factor hope this helps
