When the Sun is directly overhead, a hawk dives toward the ground with a constant velocity of 4.75 m/s at 59.5° below the horizontal. Calculate the speed of her shadow on the level ground. A picture to go along with the answer would be really appreciated as well because I am having a hard time visualising this.
Avoid the weight of the bat, since it is so much less than the force of the bat. Select the direction of the incoming ball as positive direction.
Find the magnitude of book's velocity, just before the book reaches the floor. Find the direction of book's velocity, just before the book reaches the floor.
A cannon tilted upward at = 33 fires the cannonball with a speed of 99. At that instant, what is the component of the cannonball's velocity parallel to the ground.

Hakeem throws an 8.50 g ball straight down from a height of 2.0 m. The ball strikes the floor at the speed of 7.5 m/s. What was the initial speed of the ball? Suppose that air resistance is negligible.
At t = 0 a grinding wheel has an angular velocity of 23.0 rad/s. It has a constant angular acceleration of 31.0 rad/s2 until a circuit breaker trips at t = 2.00 s. From then on, it turns by 432 rad as it coasts to a stop at constant angular accele..
