A 20 kg crate is allowed to slide down a 60-m long smooth inclined plane which is 30° with the horizontal. At the bottom of the inclined plane, the crate is allowed to slide horizontally with the ground where the coefficient of friction between the crate and the ground is 0.15. After 1 m, the crate would meet a coil with a spring constant of 1000 N/m. (Assume that the friction no longer acts as the crate hits the spring).Calculate...

Question 2 A 50 kg skateboarder is planning a trick for an upcoming competition. She starts out riding her 7 kg skateboard with initial speed of 2.5 m/s. She and the skateboard then slide down a slope of height 3 meters. At the bottom of the slope, she steps from the first skateboard onto a second stationary 7 kg. skateboard, leaving the first skateboard moving at half the speed it was before the switch. Finally, riding...

A mass m = 1 kg slides down a θ = 30◦ inclined plane from a
height of 5 m. At the bottom of the incline, it collides with
another mass M = 3 kg, and the latter is initially at rest as shown
in Fig. 3. The surface to the right of the inclined plane on which
the 3 kg (green) mass sits is horizontal.
(a) The inclined surface is frictionless. Conserve energy to
find the velocity of the...

A 4.40-kg block is set into motion up an inclined plane with an initial speed of Vi = 8.20 m/s (see figure below). The block comes to rest after traveling d = 3.00 m along the plane, which is inclined at an angle of 0 = 30.0° to the horizontal. (a) For this motion, determine the change in the block's kinetic energy. (b) For this motion, determine the change in potential energy of the block-Earth system. (c) Determine the friction...
