Question

Linear Kinetics Two 1000 kg race cars are travelling down a drag strip. Halfway through the race, r's #1 is traveling 190 mph and Car #2 is traveling 210 mph. Calculate each ca linear momentum: Car 2. Two sprinters are racing in the 100m dash. Sprinter 1 has a weight of 883 N and Sprinter 2 has a weight of 1000 N. 25 meters into the race, both sprinters are running at a velocity of 10 m/s. How much greater is Sprinter 2's linear momentum than Sprinter 1? 3. If a shot putter has 0.5 seconds to apply force of a 10 kg shot, how much force is required to generate a release velocity of 10 m/s?

Explanation / Answer

1) linear momentum of car1 is p1 = m1*v1

given that m1 = 1000 kg

v1 = 84.9 m/s

p1 = 1000*84.9 = 84900 kg-m/s

linear momentum of car2 is p2 = m2*v2

v2 = 93.9 m/s

p2 = m2*v2 = 1000*93.9 = 93900 kg-m/s
