Ax A ball is rolled along a ramp (not up or down the ramp) with a velocity of 1.7 m/s. As the ball rolls it also starts to roll down the ramp. If the ball has a displacement of Ax = 4.2 m in the x direction before it reaches the bottom of the ramp, what must be the angle of the ramp? Keep in mind the ramp is 3m long along its hypotenuse. What is the speed of the ball at the bottom of the ramp
