Question

An object initially at rest experience an acceleration of 9.8m/s/s. How much time will it take it to achieve a velocity of 58m/s

Answer 1

Answer: 5.91836735

Step-by-step explanation:

For a problem such as this you would use the equation:

V final = V initial +(A*T)

V final = 58 m/s

V initial = 0 (b/c object begins at rest)

A (acceleration) = 9.8 m/s/s

T (time) = X

Time is our unknown variable so you would begin by plugging in your equation with the variables given, which would be:

58 m/s = 0 + (9.8 m/s/s * X)

Then you isolate X by doing:

58 m/s = 0 + (9.8 m/s/s * X)

-0 -0

58 m/s = 9.8 m/s/s * X

(58/9.8)

Getting: 5.91836735 seconds = X as your answer
