engine cuts off. Air friction is negligible in this problem. How fast is the rocket traveling when the engine cuts off?
Select one:
O a. 480 m/s x
O b. 920 m/s
O c. 240 m/s
O d. 120 m/s
Your answer is incorrect.
The correct answer is: 120 m/s
A rock is released from rest from the top of a very high cliff and accelerates downward at g =10 m/s. Approximately how far
does the rock travel in the first 5 seconds of its free-fall? (Assume no air friction.)
