A cyclist moves along a circular path of radius 70m. If he completes one round in 11s, the total length of a path is:
Correct answer: B. 440m
- A. 40m
- B. 440m
- C. 0m
- D. 11m
Explanation
The following is the solution: The radius of the circular path, r=70m Time takes to complete one round, t=11s The total length of the path, s=2πr =2×22/7×70 =440m.

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.
