An 8.00 kilogram mass moving east at 14.4 m/s on a frictionless horizontal surface collides with a 10.0 kilogram object that is initially at rest. After the collision, the 8.00 kilogram object moves south at 4.20 m/s.
(a) Find the velocity of the 10.0 kg object after the collision?
m/s (magnitude)
° (direction)
(b) Find what percentage of the initial kinetic energy is lost in the collision?
%
