Question
Chapter 13, Problem 1PQ
(a)
To determine
The state of energy after it enters into the system where we pull a sled across a frozen lake. Also find whether the speed can remain constant or not if there is kinetic energy after doing the work.
(a)
Expert Solution
Answer to Problem 1PQ
The thermal energy of ice and sled increases and the kinetic energy of sled also increases. Also constant speed can be maintained.
Explanation of Solution
Here the situation is pulling of a sled across a frozen lake. The system here is not completely frictionless. Therefore, the thermal energy of the system increases. The sled can move in constant speed. Also the kinetic energy of the sled can be increased as extra energy can be added to the system.
Conclusion:
Therefore, the thermal energy of ice and sled increases and the kinetic energy of sled also increase and constant speed can be maintained.
(b)
To determine
The state of energy after it enters into the system where we pull a sled up a snowy hill.
(b)
Expert Solution
Answer to Problem 1PQ
Thermal energy will increase surely but the increase of kinetic energy is not sure.
Explanation of Solution
Here the sled is moved up a snowy hill. The system is not completely frictionless. So the frictional energy will increase. As the sled is moved up along a snowy hill against the gravity, the gravitational potential energy of the system will increase.
Conclusion:
Therefore, the thermal energy will increase surely but the increase of kinetic energy is not sure.
(c)
To determine
The state of energy after it enters into the system where a string wrapped around a pulley with a fixed axle is pulled.
(c)
Expert Solution
Answer to Problem 1PQ
The thermal energy of the system increases, rotational energy may increase or remain constant.
Explanation of Solution
If the surface offers friction, the thermal energy of the system increases. If the spring rotates about the axle, the rotational energy increases. If the friction dissipates energy from the system, the rotational kinetic energy may increase or remain constant.
Conclusion:
Therefore, the thermal energy of the system increases, rotational energy may increase or remain constant.
(d)
To determine
The state of energy after it enters into the system where a cart with large wheels across a flat ground is pulled.
(d)
Expert Solution
Answer to Problem 1PQ
The thermal energy of the system will increase, translational and rotational kinetic energy may also increase.
Explanation of Solution
If dissipative
Conclusion:
Therefore, the thermal energy of the system will increase, translational and rotational kinetic energy may also increase.

For each of the actions depicted below, a magnet and/or metal loop moves with velocity v→ (v→ is constant and has the same magnitude in all parts). Determine whether a current is induced in the metal loop. If so, indicate the direction of the current in the loop, either clockwise or counterclockwise when seen from the right of the loop. The axis of the magnet is lined up with the center of the loop. For the action depicted in (Figure 5), indicate the direction of the induced current in the loop (clockwise, counterclockwise or zero, when seen from the right of the loop). I know that the current is clockwise, I just dont understand why. Please fully explain why it's clockwise, Thank you
A planar double pendulum consists of two point masses \[m_1 = 1.00~\mathrm{kg}, \qquad m_2 = 1.00~\mathrm{kg}\]connected by massless, rigid rods of lengths \[L_1 = 1.00~\mathrm{m}, \qquad L_2 = 1.20~\mathrm{m}.\]The upper rod is hinged to a fixed pivot; gravity acts vertically downward with\[g = 9.81~\mathrm{m\,s^{-2}}.\]Define the generalized coordinates \(\theta_1,\theta_2\) as the angles each rod makes with thedownward vertical (positive anticlockwise, measured in radians unless stated otherwise).At \(t=0\) the system is released from rest with \[\theta_1(0)=120^{\circ}, \qquad\theta_2(0)=-10^{\circ}, \qquad\dot{\theta}_1(0)=\dot{\theta}_2(0)=0 .\]Using the exact nonlinear equations of motion (no small-angle or planar-pendulumapproximations) and assuming the rods never stretch or slip, determine the angle\(\theta_2\) at the instant\[t = 10.0~\mathrm{s}.\]Give the result in degrees, in the interval \((-180^{\circ},180^{\circ}]\).
