A baseball is thrown with an initial velocity of 37 m/s at an angle of 26 degrees above horizontal, from the top of the building which is 72 meters high.
A. What will be the horizontal and vertical components of this baseballs velocity?
B. what will be the vertical velocity of this baseball at the highest point of its trajectory?
C. What will be the horizontal velocity for this baseball at the highest point of its trajectory?
D. What is the "trajectory"?
E. how long will it take this baseball to reach its highest point?
F. What will be the highest point reached by this baseball?
G. How long will it take this baseball to reach the ground?
H. How far from the base of the building will this baseball strike the ground?
You need to use vectors because there is an angle and you know the initial velocity, and acceleration but not the final velocity. Make a picture and write out all information given to you in columns labeled X and Y directions. Then plug them into different kinematic equations and try to find the answers. These are not plug and chug problems, you have to think about them and manipulate different equations to get the correct answers.
