Question

The final velocity (v) is given by the formula v = v0 + at, where v0 is initial velocity, v is final velocity, a is acceleration, and t is time. A car moving at an initial velocity of 20 meters/second accelerates at the rate of 1.5 meters/second2 for 4 seconds. The car’s final velocity is meters/second.

Answer 1

For this case we have the following equation:
 v = v0 + at
 Where, we have the following values:
 v0 = 20 meters / second
 a = 1.5 meters / second2
 t = 4 seconds
 Substituting values we have:
 v = 20 + (1.5) * 4
 v = 26 meters / second
 Answer:
 The car's final velocity is:
 v = 26 meters / second
