Hey guys please work this out for me showing me the steps and explaining it to me- science is so not my forte.
g= 9.8m/s/s => this is what it says on top of the sheet. Do I really need it?
Neglect friction. FIND THE FORCE REQUIRED.
1) For a 50kg woman on a 20kg bicycle travelling at 6m/s to come to a halt in 2 seconds.
2) To give a mass of 25 kgs. an acceleartion of 18m/s/s.
3) To accelerate a 1500 kg space probe from 54 000 to 54900 kms/hr in 20 seconds.
