You fire a gun horizontally that is 25.0 m off the ground and the bullet goes at 200.0 m/s. Illustrate what is the time it takes for the bullet to hit the ground, how far down range does the bullet travel, and what is the resultant velocity (in m/s) and final angle?
A 59kg woman trips while walking down the street. She stumbles forward and falls onto her outstretched right hand. At the instant her hand contacts the ground her whole body is moving downward at a velocity of 9m/s and has a downward acceleration ..
An oil film with n = 1.45 floats on water. It is illuminated by white light from the sun at noon. If the film is 280 nm thick, find the wavelength and color of visible light that is most strongly reflected upward to an observer positioned above th..

A 2.0 m-long cylindrical steel wire with a cross-sectional diameter of 4.0 mm is placed over a light, frictionless pulley, with one end of the wire connected to a 5.0 kg object and the other end connected to a 3.0 kg object. By how much does the w..
The object is authorized to move on a horizontal frictionless surface. The object is released from rest when the spring is compressed 0.15 m. Find out the force on the object.
A shell, fired from a cannon, has a muzzle speed (the speed as it leaves the barrel) of 800 ft/s. The barrel makes an angle of 45o with the horizontal and, for ease; the barrel opening is assumed to be at ground level.
A boy on board a cruise ship drops a 30.0 g marble into the ocean. If the resistive force proportionality constant is 0.500 kg/s, what is the terminal speed of the marble in m/s?
Tension is maintained in a string. The observed wave speed is 25 m/s when the suspended mass is 3.0 kg. (a) What is the mass per unit length of the string? (b) What is the wave speed when the suspended mass is 1.7 kg?
what is the rms speed of the molecules. Graphically find out the distance and direction from Lake B to the base camp.
A cart carrying a vertical missile launcher moves horizontally at the constant velocity of 30.1 to the right. It launches a rocket vertically upward. The missile has an initial vertical velocity of 40.33 relative to the cart.
