| Dapper Dan,
the dangerous dart dude, got tired of his no-bull's-eye target. His neighbor
came over for a visit, and guess what happened?!
Dan's 200-g darts leave his hand with a velocity of 30 m/s. If it takes him 0.5 seconds to throw it, what average force does his hand exert on the dart? |
Impulse equals change in momentum.
The change in momentum equals
(0.2 kg)(30 m/s) = 6 kg-m/s = 6 N-s Impulse / time = Force, so
