A boy shoves his stuffed toy zebra, which has mass m, down a frictionless chute, starting at a height D above the bottom of the chute and with an initial speed of V. The toy animal emerges horizontally from the bottom of the chute and continues sliding along a horizontal surface with coefficient of kinetic friction mu. At what distance d from the bottom of the chute does the toy zebra come to rest? Express your answer in terms of...

m d[m] Problem 1 [20 points) A box of mass m = 6 kg slides down an inclined ramp of length d = 2 m as shown in the Figure. The box starts with initial speed 2 m/s at height h = 1 m from the bottom of the ramp. A constant friction force f = 3 N is applied to the box when sliding h[m] down the ramp. Consider the box of mass m, as your system. a) [5...

A box slides down a plane 8m long that is inclined at an angle of 30 degrees with the horizontal. If the box starts from rest and µ= 0.25, find a) the acceleration of the box b) its velocity at the bottom of the plane and c) the time required for it to reach the bottom. If the box in the previous problem has a mass of 60kg, how much force is needed to move it up the plane a)...

A box slides down a ramp with a constant acceleration of 0.300 m/s2. The ramp is raised 18.0o above the horizontal. Calculate the coefficient of kinetic friction between the ramp and the box. HINT: Notice that the velocity is not constant as it was in the previous problem. However, the free body diagrams for both of these problems are the same. Use the free body diagram to write out the corresponding Newton's Law equations for x and y in the...
