Question

the velocity of a particle given by v= 2t² - 6t. find the average acceleration during the time interval t = 2sec and t = 3 sec.(oowdavecjv) find the time at which acceleration becomes zero.​

Answer 1

Answer:

acceleration = -4m/s^2 (Retardation)

At t=1.5 acceleration will also 4m/s^2

Explanation:

Find velocity at t=2 and t=3 seconds

then avg acceleration formula

V2-V1

-----------

t2 - t1
