igomit [66]

Answer:

96m/s

Step-by-step explanation:

Given the velocity, v, in ft/s of an object given by the formula v=v0−32t,

Given

V = 39ft/s

t = 2secs

Required.

Initial velocity v0

Substitute the given parameters into the formula

v=v0−32t,

32 = v0-32(2)

v0 = 32+64

v0 = 96m/s

Hence the initial velocity of the object is 96m/s
