(a) What is the magnitude of the momentum of a 10,000-kg truck whose speed is 12.0 m/s? (b) What speed would a 2000-kg SUV have to attain in order to have (i) the same momentum? (ii) the same kinetic energy?
Added by Thomas H.
Step 1
0 m/s. momentum = 10,000 kg × 12.0 m/s = 120,000 kg·m/s So, the magnitude of the momentum of the truck is 120,000 kg·m/s. (b) (i) To find the speed of the SUV with the same momentum, we can use the same formula for momentum: momentum = mass × velocity We know Show more…
