Question
A baseball is hit with a speed of 30.0 m/s at an angle of 43.0 degrees. It lands on the flat roof of a 12 meter tall nearby building. If the ball was hit when it was 1.1 m above the ground, what horizontal distance does it travel before it lands on building?
Exactly 3.0s after a projectile is fired into the air from a flat ground, it is observed to have velocity v= (8.6i+4.8j) ms-1, where x is the horizontal and y axis is positive upward. Find out
(a) Horizontal angle of projectile.
(b) Its maximum height above the ground, and
(c) It`s speed and angle of motion just before it strikes the ground.
