Anna used a rock to drive a peg into the ground to put up her tent. if the rock applied a 9.5 n force in 0.50 s, what is the impulse on the peg?

The formula for impulse is as follows:

impulse = force x time

Simply substitute the known values into the equation above:

impulse = 9.5 N x 0.50 s

Simplify the right side of the equation:

impulse = 4.75 N·s

The impulse on the peg is 4.75 N·s

I hope this helps!
