Consider the incline shown in the figure with inclination angle θ and height h. The coefficient of kinetic friction between a block of mass m and the incline changes along its surface. From A to B it has a value of μ1, and from B to C its value is μ2. The block (not shown) is given an initial velocity up the incline at point A with a magnitude vA.   A) What is the value of vA for which the block will reach the top of the incline (point C) with zero kinetic energy? Your answer should be written in terms of the quantities given in the statement.   B) Show that for the block to surpass point B, the initial speed at A should satisfy the inequality  vA > √[ (2/3)gh(1+μ1cotθ) ]

During a physics inquiry, you place a 0.250kg dynamics cart on a ramp inclined at 25.0 degrees to the horizontal. The cart is initially at rest, before you pull it up the ramp with a force sensor. The force sensor exerts a force on the cart parallel to the ramp. The coefficient of friction is 0.300. Determine the force to pull the cart up the ramp at an acceleration of 1.50 m/s/s. Include a force diagram.

Two crates of fruit  are released from the top of a ramp inclined at 30 degrees from the horizontal and 4.5 meter long. The two crates consist of  an apple crate of mass 20 kg that is placed in front of a watermelon crate of mass 80 kg.  The apple crate has a coefficient of friction of 0.20 while the watermelon crate has a coefficient of friction of 0.15. How long does it take the apple crate to reach the bottom of the incline if it needs to travel a distance of 4.5 meters?
