Question: A body of mass 3kg is acted on by a force which varies as shown in the graph below The momentum acquired is given by
Options:
A) Zero
B) 5 N-s
C) 30 N-s
D) 50 N-s
Show Answer
Answer:
Correct Answer: D
Solution:
[d] momentum acquired = Area of force - time graph
$ =\frac{1}{2}\times (2)\times (10)+4\times 10=10+40=50N-s $
