Question 3) The diagram is about the motion of an object in the xy plane: Overall the object starts at point A on the +y axis, moves in the-y direction until reaching the origin of coordinates where it makes a right angle turn and moves in the +x direction until reaching point D on the x-axis. The speed is not constant and we know more detail about the motion at only four points: When t-0.00s] it is at point A...

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...
