A) 10
B) 20
C) 30
D) 40
E) 50
Correct Answer: D
Solution :
From the definition of impulse, we have \[Fdt=dp\] Momentum is area under\[F-t\]graph. \[\therefore \] \[dp=\left( \frac{1}{2}\times base\times height \right)\] \[+\left( \frac{1}{2}base\times height \right)\] \[dp=\frac{1}{2}\times 2\times 20+\frac{1}{2}\times 2\times 20\] \[dp=40\]You need to login to perform this action.
