Ralph is also swinging at the park. he has a mass of 72.6 kg, and his maximum velocity at the lowest point in his swing is 7.3 m/s. what is ralph’s maximum kinetic energy? hint: kinetic energy = 1/2 mass x velocity-squared

Abody of weight 60 kg is standing in a lift the lift going upward with a uniform velocity of 4.9 metre per second slows down and stops in two seconds then apparent weight of the body during the slow down process is
