Early one October, you go to a pumpkin patch to select your Halloween pumpkin. You lift the 3.2 kg pumpkin to a height of 1.2 m , then carry it 50.0 m (on level ground) to the check-out stand. What is the work you do on the pumpkin as you lift it from the ground and how much work do you do on the pumpkin as you carry it from the field?

When a book falls from a shelf to the ground without anyone pushing on it, no work is done on the book. true or false

How would doubling the made of an object change the objects potential energy

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
