A crazy person jumped off a 100-meter sea cliff because of climate change (it's hot, you know). He is launched up in the air at a velocity of 20m/s in a direction making an angle of 25° upward with the horizontal. a. What is the maximum height reached by the crazy person? b. What is the total time flight (between launch and touching the water surface) of the crazy person? c. What is the horizontal range of the crazy person? d. What is the magnitude of the velocity of the crazy person just before it hits the ground?
