The figure below gives the position of a 14 g block oscillating in SHM on the end of a spring. On the horizontal axis, t1 = 18 ms.
(a) What is the maximum kinetic energy of the block? (Hint:
Measuring a slope will probably not be very accurate. Can you think
of another approach?)
(b) How many times per second is the maximum kinetic energy
reached?

In the figure below, a 4.0 kg block is accelerated from rest by a compressed spring of spring constant 600 N/m. The block leaves the spring at the spring's relaxed length and then travels over a horizontal floor with a coefficient of kinetic friction uk= 0.30.The frictional force stops the block in the distance of D = 8.0 m. -- No friction a) Find the increase in the thermal energy of the block-floor system b) What is the original compression...

The block in the figure lies on a horizontal frictionless surface, and the spring constant is 50 N/m. Initially, the spring is at its relaxed length and the block is stationary at position x = 0. Then an applied force with a constant magnitude of 3.0 N pulls the block in the positive direction of the x axis, stretching the spring until the block stops. When that stopping...

Please work out 3 clearly and with units. Thanks!
1. A 10-g bullet travels vertically upwards at 1000 m/s, then strikes and passes through a 2.0-kg block initially at rest. The bullet emerges from the block with a speed of 400 m/s because it transfers momentum to the block. (a) How much momentum did the block gain? (b) How fast is the block now moving, and what is its kinetic energy? (c) Using energy considerations only, to what maximum height...
