(b)
The speed of object after
Answer to Problem 36QAP
The speed of object after
Explanation of Solution
The area under a force versus time curve is equal to the change in momentum of the object.
We break the graph into different parts two obtain the area so that we can calculate the momentum of the object.
since the object starts from rest, we have initial velocity of the object as zero that gives initial momentum of the object equals to zero.
Conclusion:
The speed of object is

The skater crosses the finish line of a straight-line race with speed vi and then slows down by coasting on his skates. Show that the skaters speed at any time t after crossing the finish line is v(t) = vi/(1 + ktvi).arrow_forward
