A billiard ball moving at 5.0m/s strikes a stationary ball of the same mass.  After the collision, the ball moves at 4.33m/s at an angle of 30.0° with respect to the original line of motion.  Assuming an elastic collision, find the magnitude and direction of the struck ball’s velocity.

A person is pushing a car down a horizontal road. She exerts a force of 4000 N at an angle of 10°. If the total mass of the car is 1000 kg and the µ between the car and the road is -0.35, how much work is done if the car travels 100 meters?

 Q4- The Moon orbits the Earth along a path of radius 3.84 x 108 m. The mass of the Moon is 7.35 x 1022 kg, and the mass of the Earth is 6.00 x 1024 kg. (AC 1.2) a) The gravitational force of attraction between the Earth and the Moon keeps the Moon in orbit. Calculate the size of this force. b) A rocket of mass 42000kg is fired from Earth to the Moon. What is the net gravitational force on the rocket when it is 3 x 108 m from the centre of the Earth?
