Given that a projectile is fired at an angle theta to the horizontal with initial velocity U. If g=acceleration due to gravity find the expression for the horizontal distance X and the vertical height H travelled after a time T.​

Two vectors are shown. which statement best compares the vectors? vector x has greater magnitude than vector y. vector y has greater magnitude than vector x. the vectors have the same displacement. the vectors have the same direction.

Could someone me find the answer to this problem.

Explain earth's motion, using the terms "precession" and "rotation" in your answer.
