A size-5 soccer ball of diameter 22.6 and mass 426 rolls up a hill without slipping, reaching a maximum height of 3.50 above the base of the hill. We can model this ball as a thin-walled hollow sphere. At what rate was it rotating at the base of the hill? How much rotational kinetic energy did it then have?
An object of mass 12.0 kg and traveling 10.0 m/s to the right collides with a second object of mass 24.0 kg traveling 13.0 m/s to the left. how much energy went into heat and sound
A gas expands from I to F. The energy added to the gas by heat is 442 J when the gas goes from I to F along the diagonal path. What is the change in internal energy of the gas.
The transverse displacement (y) of a wave is given as a function of position (x in meters) and time (t in seconds) by the expression to the right. Determine the wavelength, frequency, period, and phase constant of this waveform.
Two capacitors are connected parallel to each other. Let C1 = 3.50 ?F, C2 = 5.50 ?F be their capacitances, Calculate the potential difference across each capacitor: V1 = and V2 =
Imagine a "free" electron and a "free" proton held midway between the plates of a charged equivalent plate capacitor. When released, how do their accelerations and directions travel compare.
A generator produces 60 A of current at 120 V. The voltage is usually stepped up to 4500 V by a transformer and transmitted through a power line of total resistance 1.0 Ù
A merry go round at a children's playground can be approximated as a uniform circular disc with a diameter of 3.72 m and a mass of 288 kg. A constant force of 178 N is applied perpendicular to the outer edge of the merrygoround. How long does it t..
A ball of mass m=0.5 kg and radius r=0.02m is pushed against a spring of force constant 200N/m, What is the speed of the rolling ball when it leaves the spring
Three parallel wires are parallel to the y-axis, and all are at z=0. The first is glued to the table top at x=0 and carries a current of 3 amps in the positive y direction. What is the initial acceleration(magnitude and direction) of the second wir..
A star ship is circling a distant planet of radius. The astronauts determine that the acceleration because of gravity at their altitude is half the value at the planet's surface. How far above the surface are they orbiting? Your reply would be a m..
A shell is fired at an angle of 20 degree above the horizontal at a velocity of 200 m/s a) what is the range. b) What is its velocity at highest point of the trajectory.
A horse walks in a 24 ft diameter circle, making 144 trips around the circle in one hour. Using the currently accepted value of 746 watts for 1 horsepower, calculate the force in pounds with which the horse must have been pulling.
