Slide 17

What are some approximate numbers

Car mass 1500 kg

Car speed 60 mph 33m/s

Bug mass 1 g = .001 kg

Bug speed bug speed 10 mph 7 m/s

Slide 18

1500*33 + .001*-7 = ( 1500 + .001)v

49500+ -.007 = 1500.001*v

49499.993=1500.01*v

32.99= v

So the car’s velocity changes from 33 to 32.99, while the bug changes from -1 to 32.99
