A 1000 kg aircraft going 25 m/s collides with a 1500 kg aircraft that is parked. They stick together after the collision and are going 10 m/s after the collision. If they skid for 6seconds before stopping, how far did they skid?
A solenoid 10.0 cm in diameter and 75.4 cm long is made from copper wire of diameter 0.100 cm, What power must be delivered to the solenoid if it is to produce a field of 7.60 mT at its center
A block has an initial speed V(o) > 0 on a linear trajectory on the surface with friction coefficient u and air resistance (F = cv^2). Derive an equation that will represent the velocity (V) as a function of the position of the block (x). So V(x).
Two charged bodies exert a force of .145N on each other. If they are now moved so they are one fourth as far apart, what force is exerted.
The three principal visible spectral lines from hydrogen have wavelengths 434 nm, 486 nm, and 656 nm. Find the angular position of the third spectral line in hydrogen
It's found that string is set into oscillation only at the frequency 880 Hz and 1320 Hz as the frequency of an oscillator is varied over the range 500-1500 Hz. What is the tension in the string.
An object is oscilliating on a spring with a period of 4.60 s . At time t= 0.00 s the object has zero speed and is at x = 8.30 cm . What is the acceleration of the object at t= 2.50 s ?
What is the relationship between the light emitted by an atom and the energies of the electrons in the atom?
Suppose the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you find in part (a). Illustrate what should be the maximum speed of the car so it can round the curve safely?
Two protons are located on the x-axis at 1.0m and on the y-axis at 1.5m. Determine the electric potential energy of a third proton located at the origin
A wheel has eight spokes and a radius of 33.0 . It is mounted on a fixed axle and is spinning at 2.80 . You want to shoot a 38.0 long arrow through the wheel, parallel to this axle, without hitting any of the spokes. Assume that the arrow and the ..
A uniform electric field of magnitude 445 N/C pointing in the positive x-direction acts on an electron, that is initially at rest. The electron has moved 3.10 cm.
