The average angular acceleration of the fan is
The number of revolutions after time is given by
Acceleration is assumed to be constant, so and over the 2 second interval we have
so the answer is A.
D. Volume will increase
Volume and temperature are directly proportional for a gas.
Answer:
Explanation:
Impulse results in change of momentum
FΔt = mΔv
F = 0.030(50.0 - 0) / 0.010 = 150 N
The vertical portion of that force adds to his weight on the ice
Fmax = 60.00(9.81) + 150sin30 = 663.6 N
As this is above the ice strength, He takes a cold dip.
It depends when you look at a pichture it could possibly help.
