An 8.00 kilogram mass moving east at 14.9 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 3.60 m/s.
(a) Find what is the velocity of the 10.0 kilogram object after the collision?
m/s (magnitude)
° (direction)
(b) Obtain what percentage of the initial kinetic energy is lost in the collision?
%
