Question

Kyle is flying a helicopter and is rising at 5.0m/s when he releases the bag. After 2.0s

a) what is the bag's velocity?
b) how far has the bag fallen?
c) how far below from the helicopter is the bag?

Answer 1

1) v=u+gt = -5 +10*2=15 m/s
2) r=ut+gt^2/2=-5*2+10*2^2/2=-10+20=10m
3) r of heli= vt =5*2=10m
So 10m by bag from answer number 2 plus additional 10m by helicopter equals 20m

Answer 2

a. What is the bag’s velocity?
Answer: 25 m/s

b. How far has the bag fallen?
Answer: -30 m

c. How far below the helicopter is the bag?
Answer: 20 m below the helicopter
