Question

A car strikes a wall with an average force of 1.23x10^7N(S) over an interval of 21.0 ms calculate the impulse.

Answer 1

The equation for impulse is:\[J=F _{avg} \Delta t\]where J is the impulse; Favg is the average force; and ∆t is the interval over which that force is exerted.

Answer 2

is \[\Delta t\] in seconds? and thanks :)

Answer 3

Yes, so you'll need to convert 21.0ms to seconds.
