Draw two diagrams for the situation where a moving train (with initial speed v0) collides elastically with a target train that is not intially moving, and the trains use their springy bumpers to bounce off each other without damage. one diagram should show the instant just before the collision and the other the instant just after the collision. Assume the trains have different masses (m moving and m target) Make sure you identify your isolated system. Show that the final velocity of each train will be:
v target= 2v0/ (1+ mtarget/moving)
v moving= (m moving - m target)/ (m moving + m target) v0
As a positron moves through a region of space, its speed increases from 2.80 X10^6 m/s to 8.00 X10^6 m/s. The electric force is the only force acting on the positron. Across what potential difference did the positron travel?
Suppose the peak of a particular star's spectrum occurs at about 6000 Å (Angstrom). (a) Use Wien's law to calculate the star's surface temperature. (b) If this star were a factor of four hotter, at what wavelength would its spectrum peak? In what ..
Which has a greater packing fraction, a diamond crystal structure or a copper crystal structure, how much empty space would be left in each structure
The ball strikes the floor at a speed of 7.8 m/s. Illustrate what was the initial speed of the ball? Assume that air resistance is negligible.
Coherent light from a sodium-vapor lamp is passed through a filter that blocks everything except for light of single wavelength. It then falls on two slits separated by 0.410 . In resulting interference pattern on a screen 2.10 away, adjacent bri..
A point charge q = 1.45 nC is placed in the center of a spherical cavity of an isolated spherical conductor of inner radius 4 cm and outter radius 12cm
A car of mass 1110 kg travels at a speed of 20 ms-1 along a straight road. The driver sees a red traffic light ahead, and applies brakes. The coefficient of friction between the car tyres and the road is 0.83. Take the acceleration due to gravity to ..
What is the propotion of the mass of these excess electrons to the mass of the penny.
A lens which is 40.0 cm from an object forms an image of the object on a card 20.0 cm away. Determine what is the focal length of the lens? If the height of the image is .75 cm, what is the height of the object?
An object with a charge of 0.980 µC is placed at the center of a regular icosahedron with 20 equivalent surfaces. What is the electric flux through one surface of the icosahedron?
an oxygen ion O2- is moving with a speed of 322 m/s in a direction perpendicular to a magnetic field of magnitude B, what is B
A gun shoots bullets that leave the muzzle with a speed of 338 m/s. If a bullet is to hit a target 104-m away at the level of the muzzle, the gun should be aimed at a point above the goal.
