How long (time) would you travel up (Velocity final = 0) if you jump up on a trampoline (Acceleration of gravity on earth is - 9.8 m/s^2), if your initial velocity was 6 m/s?

How high (Distance) would you travel up in the above problem if your initial velocity was 6 m/s and the acceleration on the earth is -9.8 m/s^2? Use your answer from Question 1 for your Time.

You throw a ball to a friend that is 25 meters away (Distance). How fast was the ball traveling forward (velocity initial) when it left your hand if it takes 4 seconds (Time) to reach your friend? (Acceleration = 0)

You throw a ball to a friend. How high did it go (Distance) if it takes 4 seconds to reach him (YOUR TIME = 2 SECOND), acceleration from gravity on earth is always -9.8 m/s^2, and your velocity initial is your answer from Question 4. question 4's answer was 6.25
