how long does it take to fall 20m?
4.9 t^2 = 20
his horizontal speed is constant, so he travels 3t meters. Is 3t>10?
Repeat with 5t
4. Rico signed up for a cliff diving competition on year 2022. As a training, he wants to find out if he is fast enough while mid-air for him to reach a spot in the water which is 10 meters away from the base of a 20 meter high cliff. If he dives with an initial horizontal velocity of 3 m/s, will he be able to reach the 10 meter spot? If he dives again with an initial horizontal velocity of 5 m/s, will he be able to reach the 10 meter spot? Prove your answer by computing the different components.
