The velocity at

See the step by step solution

Step by Step Solution

Step 1 : Given information.

Mass (m) = time (t) = , force vs. time graph :

Step 2 : Calculation.

For velocity at a given time :

Area under the curve = Area of the triangle.

Step 3 : Continuation of calculation.

Now,

Area between the is zero,

So,

Step 4 : Final answer.

The object's velocity at
