a motor car accelerates for 10seconds to attain a velocity of 20m/s2 . it continues with uniform velocity for a further 20seconds and then decelerates so that it steps in 20seconds. calculate the acceleration and deceleration?
Answered by Steve
acceleration = 20m/s รท 10s = 2 m/s^2
deceleration takes twice as long, so it is half as much.

A Car Starting From Rest Is Acceleratted Uniformly To A Velocity Of 100.8K/L covert this to meter persecond.

A motor car accelerates for 10sec to attain a
velocity of 20m/s. it continues with uniform
velocity for a further 20sec and then decelerates
so that it stops in 20sec. calculate
I) acceleration
ii) deceleration
iii) the distance traveled?
