A skier of mass
m started at rest and slides down over a
frictionless inclined plane. He reached the bottom at a speed of 20
m/s. Then reached the second inclined plan. If the second inclined
plane has a friction coefficient of 0.2 and inclined at angle of
20°. How far does he slide on it before coming momentarily to
rest?
hi =? 20°

4. Starting from rest, a ball slide down a plane which is inclined at an angle of 30° with respect to the horizontal. At the bottom speed of the ball is 25 ms. If the coefficient of kinetic friction between the ball and the plane is 0.20. find: a) the acceleration of the ball down the plane, and b) how far down the plane the ball has moved? n. (8 pts)

1 If an object is on a frictionless inclined plane, how many forces act on the body? Draw a diagram indicating the forces. 2 Consider an Object on an Inclined plane at an angle of 5 degrees and also at an angle of 10 degrees. In which case will the object move faster down the incline? 3 Explain how you will calculate the acceleration of the cart from a velocity -time graph. If in the experiment, the length of the...

Figure 4: Top view of force table. (3) Figure 5 is an inclined-plane system that will be stud- ied in the first part of this experiment. As labelled in the figure, the x (y) direction is parallel (perpendicular) to the inclined plane, and the gravitational acceleration is downward. If the hanging mass m is too small, the block mass M on the inclined plane slides down. When the hanging mass is gradually increased to a lower-bound value mi such that...

A block is at rest on an inclined plane (shown in diagram). Coefficients of friction are μ-02, μ,-0.17. Gravity is 9.8 m/s2 Okg What is the normal force on the box? Let's assume friction were not a factor-the box would slide down the ramp. What is the magnitude of the force that causes the box to24 down the ramp? What is the static friction force on the box? Will the box slide without being pushed down the ramp? What is...

A box slides down a plane 8m long that is inclined at an angle of 30 degrees with the horizontal. If the box starts from rest and µ= 0.25, find a) the acceleration of the box b) its velocity at the bottom of the plane and c) the time required for it to reach the bottom. If the box in the previous problem has a mass of 60kg, how much force is needed to move it up the plane a)...

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 sphere goes up rolling on an inclined plane (maximum height is H) with an angle of 30 °. When the sphere is at the foot of the plane, its center of mass moves with a velocity of 5 m / s. How far will the sphere go up the inclined plane? How long will it take to return to the starting point?
