Question 40472: Could someone please help me understand how to solve this question? I really need help.
Velocity. If a ball is dropped from a height of 256 ft, then the formula
v(t) = -32t
expresses it�s velocity v(t) in feet per second as a function of time t in seconds.
a) Find v(0), the velocity of the ball at the time t = 0.
b) Find v(4).

a) Find v(0), the velocity of the ball at the time t = 0.
v(t) = -32t
v(t) = -32(0)
v(t) = 0
b) Find v(4).
v(t) = -32t
v(t) = -32(4)
v(t) = -128
