A particle travels with velocity of 4 msec for 0 lessthanore

A particle travels with velocity of 4 m/sec for 0 lessthanorequalto t lessthanorequalto 3 and a velocity of 2 m/sec for 3

Solution

(a) Here given that between 0 to 3 seconds velocity = 4m/sec

So in first 2 seconds it travels = 2\\times 4=8m.

(b) Here given that between 0 to 3 seconds velocity = 4m/sec

So in first 3 seconds it travels = 3\\times 4=12m.

   and between 3 to 5 seconds its velocity = 2m/sec

So between 3second tp 4second it travels 2m.

Therefore total distance traveled in first 4 seconds = 12m+2m=14m (Answer)
