Answer :
666.6667 N force did he apply.
When two or more items interact, it creates a push or pull between them and is known as a force. Whenever a force is present, it always has a direction. The drag caused by a surface's interaction with air and the force caused by friction between two objects is two examples of opposing forces. The impulse is described as the result of time and force.
Impulse (I) equals F * t.
As the impulse is given to us, which is:
I equal 100 ns, and t is 0.15 s.
So, the necessary force is:
F = I/t
F = 100/0.15
F = 666.6667 N
