Q. If the bullet has a mass of 21.5 and a speed of 310 , how high will the block rise into the air after the bullet becomes embedded in it?
Q. Four particles with masses m1 = 19 kg, m2 = 29 kg, m3 = 2 kg, and m4 = 39 kg sit on a very light (massless) metal sheet and are arranged. Find the moment of inertia of this system with the pivot at the following point. (Assume the rotation axis is parallel to the z direction, perpendicular to the plane of the drawing)
If the speed of sound is 1100 feet per second and a tuning fork oscillates at 440 cycles per second, what is the wavelength of sound produced.

An airplane is flying with a velocity of 93at an angle of 25 above the horizontal. When the plane is a distance 103 directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment.
You travel to an alien planet. The local population tries very hard to tell you what gravity is on the surface. You cannot understand them, and do not have a tool to calculate gravity directly. You also ran out of water. They offer a liquid to you, o..
The yellow light from a helium discharge tube has a wavelength of 587.50. When this light illuminates a certain diffraction grating it produces a first-order principal maximum at an angle of 1.050.
2.0 kg ball moving with a speed of 3.0 m/s hits, elastically, an identical stationary ball as shown. If the first ball moves away with angle 30° to the original path,
The diffraction pattern produced by the aperture is observed on a screen at a distance of 4 m from the aperture. The power density at the centre of diffraction pattern is measured to be 7 W/m2.
A basketball player makes a jump shot. The 0.600 kg ball is released at a height of 2.00 m above the floor with a speed of 7.20 m/s. The ball goes through the net 3.10 m above the floor at a speed of 4.20 m/s Find the work done on the ball by air ..
