Homework Answers
From the conservation of energy, at any point of its motion total energy is constant. But there is a possibility to transform kinetic energy to potential energy and vie versa.
So , when the object at highest point that is maximum height kinetic energy is zero, so the total energy is potential energy.so potential energy is maximum at the maximum height.
When the ball is returned its initial position then its potential energy is zero, so the total enegry is kinetic energy.
At the point of projection kinetic energy is maximum.

1. A piece of rock is thrown into a pile of sand. How is energy conserved in this case? a Kinetic energy at the maximum height is converted to potential energy and when it touches the ground, it changes partially to work and heat. b. Potential energy at the maximum height is converted to translational kinetic energy and when it touches the ground, it is lost. c. Potential energy at the maximum height is converted to translational kinetic energy and...

The energy of motion is called: Kinetic energy. potential energy, inertial energy. Power. In an inelastic collision: momentum is conserved. kinetic energy is conserved, both (a) and (b). If the velocity of a moving object is doubled and its mass is cut in half, the kinetic energy of the object is; remains the same, doubled quadrupled, cut in half. When the net work done on an object is speed of the object is me on an object is zero; the...

An object that falls from the roof of a building starts with potential energy that becomes kinetic energy as the object falls. When the object strikes the ground, some of the kinetic energy is dissipated into the atomic-level motion of the particles that make up the object, and its temperature increases. If a 1.10 kg piece of iron fell from the roof of a building that was 24.0 m tall, what is the maximum temperature change (in °C) that it...

A ball is thrown straight up such that it leaves your hand with 200 Joules of kinetic energy. Suppose we choose the ball + Earth as our system and we use the height of the ball when it leaves your hand as h = 0. Answer the questions below ignoring air resistance. Initial gravitational potential energy when the ball leaves your hand = Kinetic energy when the ball is half way to its maximum height = j. Gravitational potential energy...
