Question #4: A crate is launched up a rough ramp with a velocity of 3 m/s. The ramp is inclined at an angle of 35° above the horizontal, and there is friction between the crate and the ramp. The crate comes momentarily to rest when it reaches the top of the ramp, 24 cm above the floor, and then slides back down the ramp again. 3 m/s 24 cm 35° Part A: Find the magnitude of the crate's acceleration while it is traveling up the ramp. Part B: Find the coefficient of kinetic friction between the crate and the ramp Part C: Give the maximum value for the coefficient of static friction between the crate and the ramp. Part D: Find the speed of the crate when it returns to the bottom of the ramp.
