Q: A baseball is pitched with an initial speed of 8 m/s at an angle of 50 degrees above the horizontal.
1. What is the speed of the ball when it comes back to the same horizontal level?
2. What is the initial verticle component of the baseball?
3. When the ball reaches its MAX height, how does the speed compare to the initial speed?
a. is 0 b.is less than initial c. equal to the initial d. greater than initial
4. If the initial speed was the same but the launch angle was increased how would the horizontal displacement be when it returns to the same horizontal level?
a. it would be smaller b. it would be greater c. can't find out d. unchanged
6. What describes the horizontal component of the velocity of a projectile
a. it is a constant b. constantly increases c. change in direction d. equal to the verticle velocity

Explore A baseball is thrown from the top of a tall building with an initial velocity of 10 m/s from a height of h= 11.5 m above the ground. Find its speed when it reaches the ground (a) if its launch angle is 37°, and (b) if it is launched horizontally. Conceptualize As the baseball moves upward and to the right, the force of gravity accelerates it downward. The vertical component of its velocity decreases in magnitude until the baseball...

A baseball is hit into the air at an initial speed of 30.5 m/s and an angle of 43.2 ° above the horizontal. At the same time, the center fielder starts running and catches the ball on its way down when the ball is 0.961 m above the level at which it was hit. If the center fielder is initially 1.25 x 102 m from home plate, what must be his average speed?
