The velocity-time graph of a moving object is given in figure. The maximum acceleration is:
Correct answer: D. 6 cm/s²
- A. 1 cm/s²
- B. 2 cm/s²
- C. 3 cm/s²
- D. 6 cm/s²
Explanation
From 30s to 40s, velocity rises from 20m/s to 80m/s in 10s. So, a =(80-20)/10 = 6cm/s2. Hence, the maximum acceleration is 6cm/s².

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.
