| Dapper Dan
does darts daringly. Blindfolded! This time, however, in the interest of
physics accuracy, he's looking as carefully as possible for the bullseye.
It's missing! Gosh! That's no bull! (That's terribull!!!)
If the 50-g dart leaves Dan's hand with a velocity of 30 m/s, what impulse acted to give it its momentum? |
Impulse equals change in momentum.
The momentum of the dart leaving Dan's hand is
mv = (0.05 kg)(30 m/s) = 1.5 kg-m/s. Therefore the impulse is 1.5 N-s |
