Please help asap!- Motion problems
I am stuck on these questions, please can some one help asap!
1. A ball is thrown horizontally from the top of a building 32.5 m high. The ball strikes the ground at a point 96.9 m from the base of the building. The acceleration of gravity is 9.8 m/s^2. Find the time the ball is in motion. Find the initial velocity of the ball. Find the x and y components of its velocity just before it strikes the ground.
2. A projectile is fired straight upward at 135 m/s. How fast is it moving at the instant it reaches the top of its trajectory? How fast is it moving at the instant it reaches the top of its trajectory if the particle is fired upward at 33 degrees from the horizontal?
