Questions 53. A car starts from rest and accelerate uniformly at the rate of 5.0m/s². Calculate it's magnitude of its velocity after moving through 100m

NECO 2007; Ans : 31.62m/s

SOLUTIONS 

Initial velocity u =0

Acceleration a = 5.0m/s²

Distance s = 100m/s

V² = u² + 2as

V² = 0² + 2(5)(100)

V² = 10 X 100

V² = 1000

V = √1000

V = 32.623m/s ANSWER
