Answer:
sure, do you have more detailed of the assignments...?
Explanation:
Answer:
He can figure out if they heat to the same temp with the thermometer.
Explanation:
They have different boiling points and heat up at different rates so they would have different temps at the same time
Velocity, va2 = 10.5 ft/s
<u>Explanation:</u>
From the figure:
Length of the cable = Sa + 2Sb = l
∴ vₐ = -2vb
Applying the principle of Impulse and momentum in x-direction

Limit is t1 to t2
-(1)
Applying the principle of Impulse and momentum in y-direction

Limit is t1 to t2
-(2)
Solving equation (1) and (2), we obtain
T = 1.6lb
va2 = 10.5 ft/s
