The velocity of an object increases from 0 to 10 m/s in 2 seconds. The distance covered by the object is _.
Correct answer: A. 10 m
- A. 10 m
- B. 7.5 m
- C. 05 m
- D. 2.5 m
Explanation
Compute the value of acceleration, a, given that:Initial velocity=u=0Final velocity=v=10Time taken=t=2a=(u+v)/ta=(0+10)/2; a=5Now, use the equation:S=ut+0.5at2S=0+0.5(5)(22)S=10

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.
