Calculate how far a ball will travel horizontally if the ball reaches a high of 1.5 m above the ground and is thrown at a horizontal velocity of 45.0 m/s. assume that the ball is caught at the same height it is thrown and that there is no air resistance.

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration

The direction of the current in an alternating current circuit remains constant. is direct. changes repeatedly. changes randomly.
