The acceleration of an object which starts from rest to reach 20 m/s in 10 sec is:
Correct answer: A. 2 m/s2
- A. 2 m/s2
- B. 10 m/s2
- C. 1 m/s2
- D. 2 m2s2
Explanation
vi=0 ms-1vf=20 ms-1t=10 sa= ?a=vf-vi/ta=20-0/10a=2ms-2

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.
