Calculate the initial speed of the van

Reference no: EM13492965

Small rockets are used to make tiny adjustments in the speeds of satellites. One such rocket has a thrust of 35 N. If it is fired to change the velocity of a 71900 kg spacecraft by 63 cm/s, how long should it be fired?

A 2590-kg van runs into the back of a 821-kg compact car at rest. They move off together at 8.5 m/s. Assuming the friction with the road is negligible, calculate the initial speed of the van.
