In the graph, the acceleration of a person from 10.0 to 15.0 seconds is:
Correct answer: B. 2 m/s2
- A. 0 m/s2
- B. 2 m/s2
- C. 4 m/s2
- D. 6 m/s2
Explanation
Solution: a = Δv / Δt.Determine the change in velocity (Δv) by subtracting the initial velocity (vi) from the final velocity (vf). Determine the change in time (Δt) by subtracting the initial time (ti) from the final time (tf). a= (30-20)/5= 2 m/s2 Hence, the answer is option b.

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.
