Answer:
0
Explanation:
The displacement is zero since it goes in a full circle and ends up where it started.
Answer:
The track's angular velocity is W2 = 4.15 in rpm
Explanation:
Momentum angular can be find
I = m*r^2
P = I*W
So to use the conservation
P1 + P2 = 0
I1*W1 + I2*W2 = 0
Solve to w2 to find the angular velocity
0.240kg*0.30m^2*0.79m/s=-1kg*0.30m^2*W2
W2 = 0.435 rad/s
W2 = 4.15 rpm
Newton’s is used to measure force.
Meters measures distance. Liters measures liquid. Kilograms measures mass & weight.
The answer is kilograms.
