Some sliding rocks approach the base of a hill with a speed of 17.0 m/sm/s . The hill rises at 40.0 ∘∘ above the horizontal and has coefficients of kinetic and static friction of 0.420 and 0.560, respectively, with these rocks. Start each part of your solution to this problem with a free-body diagram.

a.

Find the acceleration of the rocks as they slide up the hill.

b.

Once a rock reaches its highest point, will it stay there or slide down the hill?

c.

If it slides down, find its acceleration on the way down, else enter 0.

In the figure, a 5.40 kg block is sent sliding up a plane inclined at θ = 37.0° while a horizontal force   of magnitude 50.0 N acts on it. The coefficient of kinetic friction between block and plane is 0.330. What are the (a) magnitude and (b) direction (up or down the plane) of the block's acceleration? The block's initial speed is 4.30 m/s. (c) How far up the plane does the block go? (d) When it reaches its highest...

Alex the archaeologist is exploring a cave in the icy mountains of the Himalayas. She is looking for the lost Sankara Stones. The cave she is exploring has a slight incline and is iced over, forcing her to use ice cleats to explore it. After climbing 50 m into the cave, she finds what she is looking for and she takes out her ice pick and hammer to begin the delicate process of removing the stones. Little does she know...
