Answer:
At the very bottom, whnere the sag is the greatest, Jay’s acceleration is upward.
Explanation:
As Jay lands on the trampoline, Jay’s motion was dowward, the trampoline was opposing his motion and hence, caused him to reach an initial halt position. Afterwards, the trampoline causes Jay to move back into the air and therefore, the change in velocity vector act in upward direction. The acceleration vector is always align towards the change in velocity vector's direction.
To minimize loss of heat or absorption of heat from surroundings
Explanation:
Sorry if I toke a while (needed to finish some work) but here you go!!! :D.
The formula for work is
F*d
Therefore work=2.0N*3.0=6N*m
