Centrifugal acceleration of a car moving around in a circle of radius 5 m with 10 m/s velocity is _.
Correct answer: A. 20 m/s2
- A. 20 m/s2
- B. 10 m/s2
- C. 6 m/s2
- D. 11 m/s2
Explanation
Correct option:AAs we know by the formula a = v²/r where v is the velocity and r is the radius of the circle.Putting values in the above formulaa = (10m/s)2/5ma= 100m²/s2/5m a=20m/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.
