A 100 kg football linebacker is moving at 2 m/s tackles head-on an 80 kg halfback running 3 m/s. suppose the two players were initially running directly at one another. Neglecting the effects due to digging in of cleats:
1. The halfback will drive the linebacker backward.
2. The linebacker will drive the halfback backward.
3. This is a simple example of an elastic collision.
4. Neither player will drive the other backward.
a spaceship travels in a circular orbit around a planet. it applies a sudden thrust and increases its speed by a factor
A 300-g mass at the end of an ideal spring vibrates up and down in such a way that it is 2.0 cm above the tabletop at its lowest point and 16 cm above at its highest point. find the speed and acceleration of the mass when it is 12 cm above the tabl..
A 120 V rms voltage at 1000 Hz is applied to an inductor, a 2 uF capacitor and a 100 ohm resistor. what is the value of the inductor
A diverging lens with a focal length of -14 cm is placed 10 cm to the right of a converging lens with a focal length of 18 cm. An object is placed 32 cm to the left of the converging lens.
Suppose after charging a 10.9 µF capacitor to 8 V, What voltage will your voltmeter read across those two capacitors connected in parallel
A particle of charge q = e moves in a circle of radius = 0.42 m with speed v = 2.150×107 m/s. find the maximum torque exerted on the loop by a uniform magnetic field of magnitude B = 0.60 T
The two stars in a binary star system have masses 1.7×10^30 kg and 6.1×10^30 kg. What is the speed of the lightest star
an object with mass m 6.5 kg is moving with a constant velocity along the y axis v08.4 ms. suddenly a force along the x
An energy of 0.1 J is stored in the metal ball on top of a Van de Graaff generator. A spark carrying 1 micro coulomb (10^-6 C) discharges the ball. What was the ball potential relative to ground?
In some places, insect "zappers", with their blue lights, are afamiliar sight on summer nights. These devices use a high voltageto electrocute insects. One such device uses an ac voltage of 4310V, which is obtained from a secondary 120 V outlet by me..
Suppose you see two main-sequence stars of the same spectral type. Star 1 is dimmer in apparent brightness than Star 2 by a factor of 100. What can you conclude? (Overlook any effects that might be caused by interstellar dust and gas.)
