What is the deceleration of a vehicle moving in a straight line that changes its velocity from 100 km/h to a dead stop in 10 sec ?

Text Solution

Verified by Experts

Change in velocity = 0 - 100 km/h = -100km/h = `-100xx5/18=(-500)/18m//sec`.
Time = 10 sec
Deceleration = `((-500)/18)/10=(-500)/18xx1/10=(-50)/18=-2.77m//sec^(2)`
