Amber (n = 1.546) is a transparent brown-yellow fossil resin. An insect, trapped and preserved within the amber, appears to be 3.8 cm beneath the surface when viewed directly from above. How far below the surface is the insect actually located?
An artillery shell of mass 10.00 kg, lying at rest on the ground, accidentally detonates, exploding into three pieces of shrapnel. find the angle at which the remaining piece of shrapnel travels
A 1 m diameter wagon wheel consists of a thin rim having a mass of 9 kg, Determine the moment of inertia of the wagon wheel for rotation about its axis
A rocket of mass 4.5x105kg is in flight. Its thrust is directed at an angle of 49.0degrees above the horizontal and has a magnitude of6.30 x 106 N. Find the magnitude and direction of the rockets acceleration. Give thedirection as an angle above t..
In a diffraction experiment, light of 600 nm wave length produces a first-order maximum 0.350 mm from the central maximum on a distant screen. A second monochromatic source produces a third - order maximum 0.870 mm from the central maximum when it pa..
A ball is shot from the ground into the air. At a height of 9.1 m,the velocity is observed to be v = (6.5 i + 5.8 j) m/s, withi horizontal and j upward.
The rest energy E of an electron has a rest mass of 9.11 x 10 -31kg. Using Einstein's famous equation E = mc 2, find the rest energy of that electron
Firing a cannonball at 20.0m/s so that the man on the top of the castle cannot catch it. What is the relationship of the initial and final velocities of the cannonball
A solid, uniform disk of radius 0.250 meter and mass 48.7 kilogram rolls down a ramp of length 4.00 meter that makes an angle of 16.0 degree with the horizontal. Obtain the angular speed of the disk at the bottom of the ramp
The weight of a star is usually balanced by two forces: the gravitational force, acting inward, and the force created by nuclear reaction, acting outward. Over a long period of time, the force due to nuclear reactions gets weaker, causing the grav..
Write the Hamiltonian function and find Hamilton's canonical equations for the three dimensional motion of a projectile in a uniform gravitation field with no air resistance. Show that these equations lead to the same equation of motion as found in S..
A soccer ball is kicked at 30 m/s at an angle of 45 degrees above the horizon. Calculate the maximum height the ball reaches
A ball of mass m = 2.1 kg moving with a speed of v0 = 15.2 m/sstrikes an identical ball which was initially at rest. After thecollision, the incoming ball (ball 1) goes off at q1 = 28°relative to its original direction and the struck ball (ball 2)..
