Afirecracker breaks up into several pieces, one of which has a mass of 200 g and flies off along
the x-axis with a speed of 82.0 m/s. a second piece has a mass of 300 g and flies off along the
y-axis with a speed of 45.0 m/s. what are the magnitude and direction of the total momentum
of these two pieces?
1) 361 kg m/s at 56.3 from the x-axis
2) 93.5 kg m/s at 28.8 from the x-axis
3) 21.2 kg m/s at 39.5 from the x-axis
4) 361 kg m/s at 0.983 from the x-axis
5) 21.2 kg m/s at 56.3 from the x-axis

The radioactive isotope of lead, pb-209, decays at a rate proportional to the amount present at time t and has a half-life of 3.3 hours. if 1 gram of this isotope is present initially, how long will it take for 80% of the lead to decay? (round your answer to two decimal places.)
