A) 840 Newton
B) 480 Newton
C) 804 Newton
D) 408 Newton
Correct Answer: B
Solution :
When the direction of motion is reversed, change in momentum\[=m(v+u)\] \[\therefore \] Force\[=\frac{m(v+u)}{t}\] \[=\frac{15\times {{10}^{-2}}\times 32}{{{10}^{-2}}}=480\]You need to login to perform this action.
