Question
A car starts from rest and accelerates uniformly. After n seconds, it acquires the speed v. Find the distance travelled by the car in last 2s.
Solution
Given that,
Initial velocity, u = 0
Acceleration, a = ?
At t = n, the velocity of particle is v is given by the first equation of motion.
Velocity of car at t = n - 2 is given by,
Now, the distance tracvelled by the car in last two second is,
