Velocity velocity velocity
A tennis player hits a ball at ground level, giving it an initial velocity of 28.0 at 52.0 above the horizontal.
What are the horizontal and vertical components of the ball's initial velocity?
How high above the ground does the ball go?
How long does it take the ball to reach its maximum height?
What is the ball's velocity at its highest point?
What is the ball's acceleration at its highest point?
For how long a time is the ball in the air?
When this ball lands on the court, how far is it from the place where it was hit?
Angles, magnitudes and velocity
A baseball thrown at an angle of 55.0 above the horizontal strikes a building 17.0 away at a point 7.00 above the point from which it is thrown. Ignore air resistance.
Find the magnitude of the initial velocity of the baseball (the velocity with which the baseball is thrown).
Find the magnitude of the velocity of the baseball just before it strikes the building.
Find the direction of the velocity of the baseball just before it strikes the building.
