QUESTIONS 14. A particle starts from rest and moves with a constant acceleration of 0.5m/s². The distance covered by the particle in 10s is

A. 2.5m B. 5.0m C. 25.0m D. 50.0m

JAMB 1990 Ans: 25m

SOLUTIONS

Initial velocity u = 0m/s

Acceleration a = 0.5m/s²

Distance s covered = ?

Time t = 10s

Applying the second equation of motion

S = ut + ½ at²

S = 0 x 10 + ½ x 0.5 x 10²

S = 0 + ½ x 0.5 x 100

S = 0.5 X 100/2

S = 50/2

S = 25m Answer
