(a) What is the velocity at the end of this interval?
m/s
(b) At the end of this interval, a constant force of 4.7 N is applied in the -x direction for 3.4 s. What is the velocity at the end of the 3.4 s?
m/s

Do you believe the tissues in our body have memories stored in them and that those memories are passed on to others in the form of organ donations (i.e. heart, kidney, lungs, etc). When the person receives the organ donation, would those memories make that person anjoy and do things he or she had no previous knowledge of?

Two jets are traveling toward each other and are 4000 km apart. The rate of one jet is 100 km/h faster than the rate of the other. If the jets pass each other after 2.5 hours, what is the rate of the faster jet?

Also...
Ms. Driva Reck drove from her home to a service station at 48 km/h. She returned home by bicycle at 16 km/h. The entire trip took 4 hours. How far was the service station from Ms. Reck's home?

Also...
A plane on a search mission flew east from an airport, turned, and flew west back to the airport. The plane cruised at 300 km/h when flying east, and 400 km/h when flying west. The plane was in the air for 7 hours. How far from the airport did the plane travel?

FREE POINTS for anyone who attemps a good try. (10)

A force of 15N acts on a 5kg mass, another force of 6N acts in the opposite direction. If mass is initially at rest, find the time rate of change of momentum.

I'm unsure what formula to use. Of course, the prof gives homework questions COMPLETELY different from what we did in class and has us all confused!

THANKS FOR THE HELP!!
