Answer 1

The acceleration with which particle travel after 1 sec is - 2 mps²

Explanation:

Given as :

The acceleration of particle moving as a(t) = - 3 t + t²

Now, for time period of acceleration = 1 unit

So, At t = 1

A( 1 ) = - 3 ×( 1 ) + ( 1 )²

Or, A( 1 ) = - 3 + 1

∴ A( 1 ) = - 2 meter per sec²

Hence The acceleration with which particle travel after 1 sec is - 2 mps² Answer
