[omc1]

Homework Statement

A stationary 0.195 gram fly encounters the windshield of a 1375 kg automobile traveling at 116 km/h, and sticks to it. What is the change in speed of the car due to the fly

Homework Equations

V(1f)=(m1-m2/m1+m2)V(1i)+ (2m2/m1+m2)V(2i)

The Attempt at a Solution

1374.99/1375.00=(.9999x116) +0=115.998 116-115.98=0.00116 but its telling me that's wrong...

Please do not do students' homework for them here on the PF. Please instead provide hints, ask questions, find errors in their work, etc. That's made pretty clear in the Rules link at the top of the page.
