Question

The formula below gives V, the velocity in feet per second of a falling object t seconds after it has been dropped. V(t) = 32t If a piano is dropped off a cliff, how fast will it be falling after 4 seconds? A.64 feet per second B.128 feet per second C.256 feet per second D.36 feet per second

Answer 1

its B.128 Feet per second

Answer 2

I think the correct answer from the choices listed above is option B. The speed of the object falling after 4 seconds is calculated from the equation given which is V(t) = 32t would be 128 ft.

V(t) = 32t
V(t) = 32(4)
V(t) = 128 ft

Hope this answers the question. Have a nice day.
