Abicycle rider has a speed of 19.0 m/s at a height of 55.0 m above sea level when he begins coasting down hill. the mass of the rider and his bike is 88.0 kg. sea level is the zero level for measuring gravitational potential energy. ignoring friction and air resistance, what is the riderâs total mechanical energy when he coasts to a height of 25.0 m above sea level
