You are told that the linear "drag coefficient" due to air resistance for a particular object is 0.32 N · s/m and the object has a mass of 0.0020 kg. Find the magnitude of the terminal velocity of this object when dropped from rest.
Male mosquitoes in the mood for mating find female mosquitoes of their own species by listening for the characteristic "buzzing" frequency of the female's wing beats.
Clarify how Einstein's contribution to understanding the force between the earth and the moon differed from Newton's. Include a short statement of Einstein's explanation in the answer.
A major-league pitcher can throw a baseball in excess of 41.9 m/s. If a ball is thrown horizontally at this speed, how much will it drop by the time it reaches the catcher who is 18 m away from the point of release.
The ceiling is of height 3.5 m, and the balloons are launched at a velocity of 10 m/s. The acceleration of gravity is 9.8 m/s2. Evaluate at what angle must they be launched to just graze the ceiling?
Does current through a power supply increase when parallel bulbs are added? For example, if you have a circuit with one bulb and measure the current through the bulb to be 100 mA, what is the current through the power source when you add another b..
The force of gravity acting on the arm acts through point A. Identify the magnitudes of the tension force t in the deltoid muscle and the force s of the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown.

When a high speed passenger train traveling at 113 km/h rounds a bend, the engineer is shocked to see that a locomotive has improperly entered onto the track from a siding and is a distance D = 642m ahead.
A transverse pulse moves along a stretched cord of length 5.55 m having a mass of 0.130 kg. If the tension in the cord is 13.6 N, find the wave speed
Classical Mechanics: Projectile Motion, A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.80 m/s at an angle of 21.0° below the horizontal. It strikes the ground 3.00 s later.
A sound wave travels in air toward the surface of a freshwater lake and enters into the water. The frequency of the sound does npt change when the sound enters the water. The wavelength of the sound is 2.49 m in the air, and the temperature of bot..
