How to Convert Units to Solve Collision Force Problems?

[leandro_fl]

Hey guys I'm new here and also new at USA.
So I'm having some troubles with unit conversion.
How do I solve this problem? I know it's really simple but I can't figure it out.

"Estimate the magnitude of the force, in lbf, exerted on a 12-lb goose in a collision of duration 10^−3 s with an airplane taking off at 150 miles/h."

Thanks for the help

What's the problem?

One suggestion. The Rules ask you to follow the HW template when posting a problem. If you had done this, you would have shown the necessary formula(s) required for solution, which you have omitted.
