Question

A body starts from rest and gains the velocity of 5 m/s in 2 second . Is it a uniform velocity ? Explain

Answer 1

Answer:

Since the body is at rest,the initial velocity is zero. Since the body gains 10m/s in 2 seconds,the final velocity is 10m/s and time taken is 2 s. According to the equation: accerlation=(the final velocity - the initial velocity)/the time taken=(10–0)/2=5 ms^2. So the accerlation is 5 meters per second squared.
