You move a box by exerting 45 newtons of force. The total work performed was 2700 joules. How far did you move the box? d. You exert of force of 75 newtons on a rock. You push and you push, but you can’t budge it. You are exhausted! How much work did you perform?

How will the system respond to a temperature increase?

If the pressure in a gas is doubled while its volume is held constant. true or false

Aspring has a relaxed length of 33 cm (0.33 m) and its spring stiffness is 6 n/m. you glue a 76 gram block (0.076 kg) to the top of the spring, and push the block down, compressing the spring so its total length is 15 cm. you make sure the block is at rest, then at time t=0 you quickly move your hand away. the block begins to move upward, because the upward force on the block by the spring is greater than the downward force on the block by the earth. calculate y vs. time for the block during a 0.09-second interval after you release the block, by applying the momentum principle in three steps each of 0.03-second duration.
