Question

A car moves linearly with uniform retardation. If the car covers 40 m in the last 2 seconds of it's motion, what is the velocity of the car at the beginning of the last 2 second?​​

Answer 1

Answer:

Velocity at the beginning of the 2 second period would be forty metres per second. This is before the velocity goes further down to about zero metres per second in the next two seconds. Considering uniform retardation, the velocity of the car at the beginning of the last second would be 20 metres per second!
