Question

Starting from rest Leena paddles her bycycle to attain a velocity of 6 metre per second in 30 seconds then she apply brakes so that the velocity of the bicycle comes down to 4 m per second in the next 5 seconds calculate the acceleration of the bicycle in both the cases

Answer 1

Acceleration in 1st case = (6-0)/30
=6/30
=1/5
=0.2 m/s²

Acceleration in 2nd case = (4-6)/5
=-2/5
=-0.4 m/s²
