Question

In a drag race, a car takes off from rest and covers 375 meters in 5 seconds. What is the

final velocity?

Answer 1

Step-by-step explanation:

s = ut + 1/2 a t^2

375 = 0 * 5 + 1/2 * a * (5)^2

375 = 1/2 * a * 25

a = 375*2/25

a = 15* 2

a = 30m/sec^2

v = u + at

v = 0 + 30 * 5

v = 150 m/sec
