Question

As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a
surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction u,
= 0.730. Find h such that the block's speed after crossing the rough patch is 3.70 m/s.

Sam, whose mass is 80 kgkg , takes off across level snow on his jet-powered skis. The skis have a thrust of 160 NN and a coefficient of kinetic friction on snow of 0.10.1. Unfortunately, the skis run out of fuel after only 15 ss . What is Sam's top speed? Express your answer to two significant figures and include the appropriate units. How far has Sam traveled when he finally coasts to a stop? Express your answer to two significant figures and include the appropriate units.

The block slides up a slope to a height of 3.00 m and then slides across a 2.50 m long rough surface with a coefficient of kinetic friction equal to 0.325. The block continues to travel to the right and bumps into a massless spring with a spring constant (k) equal to 2320 N/m. a) How much does the spring get compressed by the block with respect to its equilibrium length? Please answer with a positive number in units of metres, with 3 sig figs. Start with conservation of energy: Er = Ei + WNC , and show all steps. b) What is the potential energy stored by the spring when the mass comes to a stop? Please show the symbolic equation and then “plug in the numbers" to give a numerical answer in units of joules with 3 sig figs. c) What happens to the potential energy stored in the spring after the block stops…

Calculate the force needed to bring a 900 kg car to rest from a speed of 90.0 km/h in a distance of 110 m (a fairly typical distance for a nonpanic stop).N(b) Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force exerted on the car and compare it with the force found in part (a), i.e. find the ratio of the force in part(b) to the force in part(a).(force in part (b) / force in part (a))

You decide to launch a rockof mass m1 using a tube containing a spring of spring constant k. When the spring is at equilibrium, it fills the entire tube. To launch a rock, you push it into the tube, compressing the spring a distance d, at which point a locking mechanism holds the spring(and the rock) in place. When the lockis released, the spring pushes the rock to the end of the tube where it will be launched into the air. The coefficient of kinetic friction between the rock and the inside surface of the tube is given by μk. You setup the launcher at an angle q above the horizontal with the spring end buried such that when the spring is compressed and locked, the rock is at ground level. a)Find the work done on the rock by non-conservative forces as it moves from the point of release to the end of the tube. Express your answer in terms of μk, m1, q, d, and any necessaryconstants. b) Find the velocity of the rockvfas it exits the launch tube in terms of μk, k, m1, q, d, and any…

A 3.00-kg block starts from rest at the top of an incline at height yo floor. It slides down the frictionless incline onto the floor, and then encounters a rough part of the floor that has a coefficient of kinetic friction u this surface before the floor is again frictionless. It then slides up another frictionless incline on the other side. (There are four situations here, labeled "0" through "3".) 2.50 m above the 0.500.
