# The kinetic energy of an object with a mass of #2 kg# constantly changes from #8 J# to #136 J# over #4 s#. What is the impulse on the object at #1 s#?

##### 1 Answer

#### Answer:

#### Explanation:

I think there is something wrong in the formulation of this question.

With Impulse defined as

then the Impulse **on the object at t= 1** is

It may be that you want the **total impulse applied** for

To evaluate **if** the rate of change of kinetic energy

then

Now

and
