Question

velocity of a motor bike is 20m/s it takes rest after 4 secs after the brake is applied find the acceleration​

Answer 1

Answer:

u (Initial Velocity) = 20 m/sec

v (final velocity) = 0 m/sec (at rest)

time (t) = 4 secs

a = (v-u) /t

a= (0 - 20) / 4

a= -20 / 4

a = -5 m/sec square

Therefore Deceleration produced is 5 m/sec square
