Part 3 Please.

(1 point) A ball is dropped from a height of 1024. The position at any time t (seconds), after the throw, can be computed using the formula y(t) : 1024 16t2 feet. Find a function to compute the velocity at any time t. v(t) : 32t Compute the velocity of the ball aftert = 1 seconds and t = 2 seconds. 0(1) 2 (feet per second) 11(2) : (feel per second) ' Part 3: When does the ball hit the ground? Hint: The hits the ground when the height is zero. Part 4
