On a distant planet whose radius is a factor of 2 times less the radius of Earth and has a mass which is a factor of 7 less than Earth, a mass of 9 kg starts on the top of an frictionless incline which has a length of 6 meters at an angle of 25 degrees and the mass is pressed into a spring. When it is let go, after a short time it is moving at 24 m/s when the force of the spring is 149 Newtons when the spring has been compressed 0.54 meters. It eventually passes over a horizontal surface at the bottom of the incline in which a 2 meter portion of the surface has friction in which the mass passes over. The coefficient of kinetic friction is 0.32. It then travels around a quarter circular, frictionless, ramp with a radius of 5 meters and gets shot vertically upwards. What is the maximum height the mass reaches relative to the horizontal surface in meters?

A spring with a spring constant of 718 N/m lies on a horizontal surface and that surface is y = 0 m to calculate the gravitational potential energy. A mass of 3 kg is compressed 0.45 meters into the spring and held still. After the mass is released it slides over a horizontal surface in which a 3.4 meter portion of the surface has friction with a coefficient of kinetic friction of 0.30. After the horizontal surface, it travels up...
On a planet having g= 10m/s^2, a 2kg mass, starting from rest, slides down a frictionless in life on to a frictionless horizontal surface. The speed of the mass on the horizontal surface is 10m/s. A) Determine the height h at which the box began its slide. consider again the same frictionless incline. However, upon reaching the horizontal surface, a surface having friction is encountered. B) If when the mass starts from the same height as in part A), the...
A mass of 5 kg is compressed 3.9 meters into one spring, held still, and released from rest. It travels over a horizontal surface, up an incline which has a height (not length) of 5 meters, and then travels over another horizontal surface. At the end of that surface is another spring with the same spring constant. The mass hits the second spring and eventually stops after compressing it 2.3 meters. What is the elastic potential energy of the second...
Problem 2 A block A of 0.5-kg rests on a horizontal, frictionless surface. The block is pressed back against a spring having a constant of k 400 N/m, compressing the spring by 12.0 cm. Then the b sreleased. The incline has a friction coefficient μ-02, and the horizontal surface has no friction. 1. Find the maximum distance d the block travels up the incline if -40 (Position C) 2. How fast is the block moving up when halfway to its...
A mass of 2 kilograms is placed on a horizontal frictionless surface against an uncompressed spring with spring constant 943.4 N/m. The inclined portion of the surface makes at an angle of 30 degrees to the horizontal and has a coefficient of kinetic friction of 0.16 with the mass. The mass is pushed against the spring until it is compressed a distance 0.12 and then released. How high (vertically), in meters, does the mass rise from the original height before...
I need a step by step on 1 and 2 so I can teach myself.
1. A solid, uniform sphere with a mass of 2.0 kg is rolling from rest down an incline plane from the top of the plane. The incline plane makes an angle of 20° with the horizontal and has a height of 2.0 m. At the bottom of the incline plane, the surface levels out to a frictionless horizontal surface. A spring with a spring constant...
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 μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s. An object with a...
A box (mass 25.8 kg) sits on a rough incline that makes an angle α = 28.1o with the horizontal. A massless string is tied to the box, runs parallel to the incline, passes over a massless, frictionless pulley, and is tied to mass M hanging on the other end. Assume μs = 0.455 is the coefficient of static friction between the box and the surface of the plane. Find the maximum value of M, in kg, for which this...

Question 1 1 pts A snowboarder passes a marker flag as she coasts up an inclined planar snow surface. The coefficient of kinetic friction between her snowboard and the snow is 0.09. She notices that she travels 40 m horizontally and 31.8m vertically (upward) before coming to rest. How fast was she moving as she passed the marker flag?
