A glider that is 180 kg is pushed by a spring with constant 3.2*10^5 N/m down a water slide track from a height of 35m in a zig zag path. Once the slide reaches the floor level track, it will be eventually stop due to friction. Friction only exists on the ground level, and the coefficient of kinetic friction here is 0.8. If 70 meters is the max distance that the glider move on this ground level track, what is the safest maximum distance that the spring can be compressed if a 20 kg person is also on the glider.
(a) Part (a) refers to the figure below. A block of mass m = 0.1 kg is going down and inclined plane with an initial speed v₁. The inclined plane makes an angle = 30° with the horizontal and the inclined plane has a kinetic friction coefficient k 0.7. After travelling a distance L = 0.8 m, the block encounters a spring with a spring constant k 20 N/m. The block comes to rest after compressing the spring an amount x = 0.3 m. What is vi, the initial speed of the block? = x = 0 oooo 0 Initial x=0 momo 0 x Initial μk 1 Vi m Mk Part a (b) Part (b) refers to the figure below. The block then goes up the inclined plane again. After the block travels a distance x, the block leaves the spring. The block continues to go up the inclined plane and the block comes to rest after it travels a distance d past the equilibrium position for the spring.

An object is subject to a nonconstant force F = (5x3 − 4x) such that the force is in newtons when x is in meters. Determine the work done on the object as a result of this force as the object moves from x = 0 to x = 1.30 ✕ 102 m.
