1. A car jumps a river that is 6m wide and lands on the right side 2m lower than the left side?
a. How much time is the car in the air?
b. how much time did it take to drop down 2m?
2. A baseball is thrown at a 32.5° angle and an initial velocity of 75 m/s. Assume no air resistance.
a. What is the vertical component of the ball’s velocity?
b. What is the horizontal component of the ball’s velocity?
c. How long until the ball hits the ground?
d. How high did the ball travel?
e. How far did the ball travel horizontally when it hit the ground?
3. Two guns are fired horizontally from the same height. Gun A can fire a bullet at 400m/s and gun B can fire a bullet at 600m/s.
a.Which bullet will hit the ground first? Or will they hit the ground at the same time? Assume bullets are fired from the same height. Explain your reasoning.
b. Which bullet will travel farther horizontally before it hits the ground? Or, will they travel the same horizontal distance? Explain your reasoning.
