A frictionless wagon is pushed from rest, with a force 60 newtons for 14 seconds. If it then strikes a wall comes to rest in 0.15 second, how much average force of the wall exert on it?
(a) 6000 N (b) 5600 N (c) 4500 N (d) 4000 N
Dear student,
Here is the solution of your asked query:
Q.15. Here, the following condition must be applied
Impulse that puts the wagon in motion=Impulse that stops the wagon
60 x 14=F x 0.15
or F=(60 x 14)/0.15
=5600 N
Thus, the average force that the wall exert on the wagon is 5600 N.
For different question ask them in different posts .
Regards
