As a car increases its speed five times when rounding a curve, how many times does the centripetal force on the car increase? A banana of mass m drops down from the height of h. Use conservation of energy (equality of initial potential energy and final kinetic energy to show that the speed of banana just before hitting the ground is . How much work is done when you push a crate horizontally with 100 N force at a distance of 10 m if the force of friction on the crate is a steady 70 N. How much KE does the crate gained in the previous
