Question

Acceleration of a cyclist moving with constant velocity of 20m/s for 15s

Answer 1

Answer:

Acceleration is the rate of change in velocity

If there is no change in veloct for 15 sec so the acceleration will be 0 m/s^2

a= dv/dt

derivative of constant will be zero.

Or

a = vf-vi/t2-t1

a= 20-20/15-0

a= 0/15

a= 0 m/s^2
