Question

What equation can be used to calculate the time of impact when you have the impulse and force applied to an object?

Answer 1

Impulse is force times time. J=Ft

Answer 2

thats not an option.
thats what i thought too.
here are the options;
@doc.brown

Answer 3

In their notation\[I=F(\Delta t)\]
Does that help?

Answer 4

so to rearrange it would it just be t=f/i or i/f? @doc.brown

Answer 5

How do you get \(\Delta t\) by itself?

Answer 6

you would add it to the other side and cancel out, correct? @doc.brown

Answer 7

Divide both sides by F.

Answer 8

meaning it's \[\Delta T = \frac{ I}{ F}\] @doc.brown ?

Answer 9

Yup

Answer 10

\[I=F(\Delta t)\]\[F(\Delta t)=I\]\[\frac{F(\Delta t)}{F}=\frac{I}{F}\]\[\frac{\cancel{F}(\Delta t)}{\cancel{F}}=\frac{I}{F}\]\[\Delta t=\frac{I}{F}\]
