Question

The final velocity (V) is given by the formula v = vo + at, where vols Initial velocity, v is final velocity, a is acceleration, and t is time.

Hola
A car moving at an initial velocity of 20 meters/second accelerates at the rate of 1.5 meters/second? for 4 seconds.
The car's final velocity is
meters/second

Answer 1

`\boxed{\sf Final \ velocity \ (v) = 26 \ m/s}`

Given:

`\sf v = v_(0) + at`

`\sf Initial \ velocity \ (v_(0)) = 20 \ m/s \\ \sf Acceleration \ (a) = 1.5 \ m/s^(2) \\ \sf Time \ (t) = 4 \ sec`

To Find:

Final velocity (v)

Explanation:

`\sf Substituting \ value \ of \ Initial \ velocity \\ \sf acceleration \ and \ time \ in \ given \ equation: \\ \\ \sf \implies v = v_(0) + at \\ \\ \sf \implies v = 20 + 1.5(4) \\ \\ \sf 1.5 * 4 = 6 : \\ \sf \implies v = 20 + \boxed{6} \\ \\ \sf 20 + 6 = 26 : \\ \sf \implies v = 26 \: m/s`
