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 would I use mgh=1/2mv^2 (and not use u because that is the velocity in the x direction ?) and then solve for v (v=sqrt(2gh)) and then use v=sqrt(vx^2 + vy^2) to find the final velocity ?
What happens to the angular velocity while the ball is in the air ?

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...

A thin ring of radius R and mass M rolls without slipping along a level track. It has an initial linear, or translational velocity (of the center of gravity) of 3.50 m/s. The ring rolls to the end of the track, where the track curves upward. The center of gravity of the ring rises to a maximum height h above its initial level. Note that V is the symbol for the linear, or translational velocity (of the center of gravity)...

Explore A baseball is thrown from the top of a tall building with an initial velocity of 10 m/s from a height of h= 11.5 m above the ground. Find its speed when it reaches the ground (a) if its launch angle is 37°, and (b) if it is launched horizontally. Conceptualize As the baseball moves upward and to the right, the force of gravity accelerates it downward. The vertical component of its velocity decreases in magnitude until the baseball...

1) Using the Work Energy Theorem, with what velocity did he take off from the floor? (Hint 1/2mv^2 = mgh Looks like the masses cancel!) Answer: 4.64 2) If he was in contact with the floor for .05 s and his initial velocity was zero and his final velocity you computed in Q 1, with what force did he push off the floor? Answer: ?? 3) With what average acceleration did the floor apply to Lebron to get him up...

A 1-kg ball in the air has an initial velocity vo = [ 10 ] i + [ -20 ] j m/s. It falls for a total time of 1 s. Assume that positive x-values are to the right and positive y-values are upward. What is the initial kinetic energy Ki of the ball? J Remember that the initial kinetic energy Ki = pi2/2m. To find the magnitude of the resultant momentum we must use the pythagorean theorem on the...
