QUESTION:
The acceleration due to gravity on the Moon is about one sixth what it is on Earth. If an object is thrown vertically upward on the Moon, how many times higher will it go than it would on Earth, assuming the same initial velocity?
ANSWER:
Step 1 of 3
The man jumps from 18m above the ground. The speed of the man increases till he touches the net which is held 1m above the ground. When the man hits the net, he starts to slow down and stops when the net touches the ground.
V0=0
?y1=17m (the displacement to the net)
?y2=1m (the height of the net to the ground)
V1=? (the velocity of the man when he hits the net)
V2=0 (the final velocity of the net when he hits the ground)
a=? (average acceleration while the net is slowing down the men)
a)
