A person is jumping on a trampoline. After coming off of the trampoline, he is in the air for 1.8 seconds. Call the initial state when the trampoline is at its lowest point with the person still on the trampoline. The final state is 1.5 seconds after the person comes off the trampoline. System: trampoline System: girl + Earth System: girl System: girl + trampoline + Earth System: girl + trampoline This question is asking if the energy of the system changes or stays constant for each of these situations, it is dealing with the work energy theorem.

1. You and a friend set up an umbrella and chairs at Torrey Pines State Beach. Your friend goes boogie boarding while you read a book. Half an hour later you are surprised to see that your friend has moved south, parallel to the beach. They are still boogie boarding the same distance from shore, in the surf zone. Why did your friend drift parallel to the beach? 2. The Sun is much more massive than the Moon, but the Moon has a bigger influence on Earth's tides than the Sun. Why is this? 3. Even when there is no wind at the beach, we still see waves. What is the source of these waves? Do not include tides, mass movement, or earthquakes in your answer. 4.

A cart with mass m is held at rest against a spring with spring constant k. It is compressed a distance x. When released from rest, it is launched through a frictionless track. It contains a vertical loop 7. with a radius of R. Find the force the track exerts on the cart when the cart goes through the top of the loop in terms of m, k, F, and R and any other constants. R k m
Classical Mechanics. A block of mass m = 5.00-kg is moving to the right with a speed of v = 2.00 m/s on a horizontal, frictionless surface. The block encounters a relaxed (that is, neither compressed nor extended) spring with spring constant k = 2,000.00 N/m. a. What is the kinetic energy of the block before hitting the spring? b. What is the kinetic energy of the block when the spring is at maximum compression? c. How much energy is stored in the spring at maximum compression? d. How far does the spring compress at its maximum compression? e. If the spring converts its stored energy completely into motion of the block, what is the speed of the block after release from the spring? f. (For this part of the problem, the surface is not frictionless) Suppose the speed of the block after release from the spring is 1.5 m/s to the left, how much work (sign and magnitude) was done by non-conservative forces between the time when the initial velocity is 2.00 m/s and the time when the velocity =…
