At the beginning of a dive, a diver is in the layout position with an angular velocity of 100°/s and a moment of inertia of 15 kg·m2. In 0.5 s, the diver tucks and increases angular velocity to 400°/s.
(a) What is the angular momentum of the diver at the beginning of the dive?
(b) What is the diver's moment of inertia in the tuck position?
(c) What was the angular acceleration of the diver moving from the layout position to the tuck position?
A more realistic car would cause the wheels to spin in a manner that would result in the ground pushing it forward with a constant force (in contrast to the constant power in Part A). If such a sports car went from zero to 30.0 in time 1.10 , how ..
If you put a 0.28 kg mass 15 cm from the axis of a massless disk, and you apply a 0.4 N force on a string wrapped at the disk's edge, what is the resulting angular acceleration
You want to examine the hairy details of your favorite pet caterpillar, using a lens of focal length 8.9 cm that you just happen to have around. what angular magnification do you achieve
A 4 kg block is acted upon by three horizontal forces. 10n (to left) 5n(short arrow to right) 25n to right. what is the horizontal acceleration of the block
A battery with an emf of 12.00 V has an internal resistance r. When connected to a resistor R, the terminal voltage is 11.70 V, What is the energy dissipated in the battery's internal resistance in 4.20 minutes
In a friendly game of handball, you hit the ball essentially at ground level and send it toward the wall with a speed of 21 m/s at an angle of 31 degrees above the horizontal
a 20 kg mass sits on an inclined plane with friction making an angle of 50 degrees with respect to the horizontal. calculate the frictional force required to keep the mass from sliding down the incline
The expression found in part (d) is a cubic equation. There are standard algebraic solutions to this type of equation, but it is sometime quicker and easier to use other methods. explain a way to get a reasonably accurate estimate of v (say, to th..
A small fly of mass 0.27 grams is caught in a spider's web. The web vibrates predominately with a frequency of 4.50 Hertz. What is the value of the effective spring constant stiffness constant for the web.
Power lines have a limit on the maximum size of the electric field they produce. In most states a maximum of 4 kN/C at about 21 m from the wires is allowed. determine how much charge per unit length is on the wire
A very long solenoid of circular cross section with radius r= 5.4cm has n= 86.0 turns/cm of wire. An electron is sitting outside the solenoid, at a distance r= 5.90 cm from the solenoid axis. What is the magnitude of the force on the electron whil..
