A force of 6 N acts on a mass of 1kg which acquire velocity of 30ms-1. The time for which the force acts is;
Correct answer: B. 5 s
- A. 26 s
- B. 5 s
- C. 6 s
- D. 2 s
Explanation
p=mv ; Δp=F x t hence, mv = Fx t F= mv/t = (1)(30)/6 = 5s

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
