A skier traveling 9.0 m/s reaches the foot of a steady upward 19 degree incline and glides 12 m up along this slope before coming to rest. What was the average coefficient of friction?
A skier traveling 11.0 m/s reaches the foot of a steady upward 21∘ incline and glides 14 m up along this slope before coming to rest. What was the average coefficient of friction?u= ?
Constants Periodic Table A spring (80 N/m) has an equilibrium length of 1.00 m. The spring is compressed to a length of 0.50 m and a mass of 2.1 kg is placed at its free end on a frictionless slope which makes an angle of 41° with respect to the horizontal. The spring is then released. 0.50 m 0 = 41° Part A If the mass is not attached to the spring, how far up the slope from the compressed...
A ski starts from rest and slides down a 24 ∘ incline 95 m long. If the coefficient of friction is 0.095, what is the ski's speed at the base of the incline? Express your answer using two significant figures. If the snow is level at the foot of the incline and has the same coefficient of friction, how far will the ski travel along the level? Use energy methods. Express your answer using two significant figures.
A 56 kg skier starts from rest at the top of a 1200-m-long trail which drops a total of 160 m from top to bottom. At the bottom, the skier is moving 11.0 m/s . How much energy was dissipated by friction? Express your answer using two significant figures.

1. A 1200kg car traveling at 11.0 m/s runs into a 920kg car traveling in the same direction at 5.00 m/s. After the collision the 1200kg car has slowed to 8.00 m/s. a) what is the final velocity of the 920kg car? 2. A bullet mass of m=0.0010kg embeds itself in a wooden block with mass M=0.999kg, which then compresses a spring (k=230 N/m) by a distance x=0.050m before coming to rest. The coefficient of kinetic friction between the block...
Phys201-1 Summer2020 <A HW (Part 1)Phys201 Problem 7.79 A block of mass m = 2.70 kg starts from the rest and slides down a 300 incline which is 3.60 m high. At the bottom, it strikes a block of mass M-7.50 kg which is at rest on a horizontal surface (Figure 1). (Assume a smooth transition at the bottom of the incline.) The collision is elastic, and friction can be ignored Determine the speed of the block with mass m2.70...
