ONLY PROBLEM 5 PLEASE.
Problem #4 - A small 50-g object starts at the bottom of a 1.7-m long frictionless ramp that is inclined 37° above the horizontal. The object is then given a quick kick such that its speed after the kick is 3.2 m/s. A. Sketch the situation. Choose an origin and coordinate axes. Write down all knowns and unknowns. B. How far up the ramp does the object go before coming back down? C. How long does...

(10%) Problem 8: An object rolls off a tabletop with a horizontal velocity vos 8 m/s. The table is at a height yo 1.85 m, above the floor. Use a coordinate system with its origin on the floor directly beneath the point where the object rolls off the table, its horizontal x-axis lying directly beneath the object's trajectory, and its vertical y-axis pointing up. 25% Part (a) How long, in...

4. An object of mass M slides down a frictionless ramp to point H. It then encounters a flat section of length L in which there is sliding friction with coefficient of friction m=a (a constant). How high up does the object go on the other side? What value of a will cause the object to stop at the end of the friction section (after moving distance L under friction)? u=0
