A fuse melts to protect a circuit.
<span>Let's first off calculate the kinetic energy using the formula 1/2MV^2. Where the mass, M, is 0.6Kg. And speed, V, is 2. Hence we have 1/2 * 0.6 * 2^2 = 1.2J. Since kinetic energy is energy due to motion; hence at point B the rubber has a KE of 1.2J and not 7.5J. So I would say that only the Mass and speed is actually true; While it's kinetic energy is not true.</span>
Answer:
Angular velocity,
Explanation:
The mass of the skater, M = 74.0 kg
Mass of each arm, ( since it is 13% of the whole body and each arm is considered)
Mass of the trunk,
Total moment of Inertia = (Moment of inertia of the arms) + (Moment of inertia of the trunks)
The final moment of inertia of the person:
According to the principle of conservation of angular momentum:
Yeah i believe it is going to be c
Answer:
Explanation:
Look at the equation for Potential Energy. PE = mass times gravity times the height. Filling in and solving for h:
34.3 = .5(9.8)h so
34.3 = 4.9h so
h = 7 meters
