Calculate the kinetic energy and potential energy of the ball half way up, when a ball of mass 0.1 kg is thrown vertically upwards with an initial speed of 20ms−1.
A ball of mass 0.20 kg is thrown vertically upwards with an initial velocity of 20 m s-1 Calculate the maximum potential energy it gains as it goes up.
Calculate the kinetic energy of a body of mass 2 kg moving with a speed of 10ms−1.
A stone of mass 64.0 g is thrown vertically upward from the ground with an initial speed of 20.0 ms-1. The gravitational potential energy at the ground level is considered to be zero. Applying the principle of conservation of energy, the potential energy attained the total energy of the stone at its halfway point can be calculated to be: (g= 10 m s-2).
