Mr Garcia is standing from a 100 ft tower where he throws a ball vertically into the air with an initial velocity of 50 feet per second. Mr Cruz, who is standing at the ground, also throws the ball that he holds vertically at the rate of 75 feet per second the same time as Mr. Garcia’s. (a) Equation of displacement as a function of time of Mr Garcia’s ball (b) Equation of displacement as a function of time of Mr Cruz’s ball (c) Equation relating the displacements of the ball of Mr Garcia and Mr Cruz (d) Determine the time in seconds when both balls be at the same height from the ground. (e) Also, determine the position of the ball of Mr Cruz (in reference to the ground) in feet when both balls are at the same height.
