Let h = 25.5 m and vi = 11.8 m/s. Find the speed of the ball just before it hits the ground. vf = m/s Find the ball's mechanical energy at the release point. KEi + PEi = J Find the ball's mechanical energy just before it hits the ground. KEf + PEf = J Remarks Notice that the final speed does not depend on the initial release angle. Kinetic energy is not a vector. The initial kinetic energy of the ball depends on the ball's initial speed, not it's velocity.

    If a ball rolls off the edge of a table at velocity u, what happens to its angular velocity ? Say if I wanted to calculate the velocity of the ball as it strikes the ground using energy methods, would I use PEi + KEi = PEf + KEf and I plug in u for the initial kinetic (1/2mu^2), mgh for initial potential, then 1/2mv^2 + 1/2 I*w^2 for the final kinetic ? And then solve for v ? Or...

    An 5kg mass is thrown with an initial velocity of 15 m/s from a height of 10 meters, at an angle of 20 degrees wrt horizontal. Using the basic kinematic equations (x(f)=x(i)+vi,xt+(1/2)axt2, and vf,x=vi,xt+axt, with similar equations along y), determine how far it has moved in x- and y-, separately, after a time of 20 seconds, and also the x- and y-components of the final velocity after t seconds, assuming the only external force acting on the mass is gravity;...

    A ball is shot from the ground into the air. At a height of 9.80 m, its velocity is v = (8.50i + 4.00j) m/s, with i horizontal and j upward. To what maximum height does the ball rise? What total horizontal distance does the ball travel? What is the magnitude of the ball's velocity just before it hits the ground? What is the angle (below the horizontal) of the ball's velocity just before it hits the ground?
