A ball that weighs 0,60 gr hangs from a 1m long string. It's pulled back and let go from a stationary position. At it's lowest point, it hits a 240 gr block on a horizontal table. The ball has a speed of 3,5m/s just before the collision.
a) At what height was the ball let go? That is, how far from
it's lowest point?
b) The block get's a 1,1m/s speed just after the collision. What
was the speed of the ball at that same time? (Just after the
collision)
c) What is the kinetic energy in this system, before and after the
collision?
d) The block slides 50cm until it stops. What is the force of
friction on the block?

A pendulum, consisting of a ball of mass m on a light
string of length 1.00 m, is swung back to a 45° angle and released
from rest. The ball swings down and, at its lowest point, collides
with a block of mass 2mthat is on a frictionless
horizontal surface.

different parts below. As usual, a good way to handle that is to

A stationary ball is let go from the top of a 75 cm long
diagonal table. It rolls down and off the edge, free falls and hits
the ground.
a) If it takes the ball 0,797 seconds to roll down the table
before it goes off the edge, what is it's average speed?
b) What is the balls speed when it goes off the edge? Formula for
even acceleration is Vm = (V0+V)/2
