Question

Unit& Impulse and Momentum- Practice Problems 1. Two average forces, Fi and F2, produce the same change in momentum. F, has a magnitude that is three times as large as that of another average force F2. The average force Fi acts for a time interval of 3.40 ms. For what time interval does F2 act? (102 ms) 2 A flying saucer is moving in deep outer space with a momentum of magnitude of 5 10' kg m/s. A retrorocket is fired to slow it down. The rocket applies a force of a nagnitude of 1.34 x 10' N to the flying saucer for a period of 10.5 s.The force is dire pposite to the saucer's motion. Determine the momentum of the saucer after the trorocket ceases to fire. (437E+7 kg m/s)

Explanation / Answer

According to the chegg guidelines I am allowed to answer only 1 question at a time.

1) T= 3.40 ms

F1 = 3 times larger than F2

so the time at which f2 acts will be

Time taken ( F2) = 3 Times * 3.40 ms = 10.20 ms================ANSWER)
