Question

Q10. (a) Define acceleration and give its SI unit.

(b) Starting from a stationary position, Shyam paddles his bicycle to attain a velocity of 10 m/s in 20 s. Then he applies brakes such that the velocity of the bicycle comes down to 5 m/s in the next 5 s. Calculate the acceleration of the bicycle in both the cases.​

Answer 1

(a)In physics or physical science, acceleration is defined as the rate of change (or derivative with respect to time) of velocity. ... In SI units, acceleration is measured in meters/second² using an accelerometer.
