(a) A 77.0 kg man floats in fresh water with 3.00% of his volume above water when his lungs are empty, and 5.00% above water when his lungs are full. Calculate the volume of air he inhales--called his lung capacity--in liters.
A cannon shoots a ball with an initial velocity of 152-m/s and a launch angle of 62°. The gravitational acceleration is 9.80 m/s2. Assuming no air resistance, how long would the cannonball stay in the air.
A rock with mass m = 3.70 kg falls from rest in a viscous medium. The rock is acted on by a net constant downward force of F = 19.3 N and by a fluid resistance force.
The side-view mirror of an automobile has a radius of curvature of 20cm. The mirror produces a virtual image one-third the size of the object. How far is the object from mirror.
A skier of mass 100 kg starts from rest and comes down a slope of constant angle 25 degrees with the horizon. What is the length of the slope
What is the period of this pendulum in the small angle approximation.
The huge volcanic eruption on the island of Krakatoa, Indonesia, in 1883 was heard on Rodrigues Island, How long did it take (in seconds) for the sound to travel to Rodrigues
What is amplitude of the subsequent oscillations
Which has a greater packing fraction, a diamond crystal structure or a copper crystal structure, how much empty space would be left in each structure
If the maximum acceleration that is tolerable for passengers in a subway train is 2.45 m/s2 and subway stations are located 840 m apart, What is the travel time between stations
A 9.8 kg object oscillates at the end of a vertical spring that has a spring constant of 1.9 * 10^4 N/m. The effect of air resistance is represented by the damping coefficient b= 3.00 Ns/m.
An object is placed in front of a diverging lens of focal length of 17.0cm, Using the thin lens equation find the distance from the lens to the object and from the lens to the image
A block of mass = 2.90 is attached to a string that is wrapped around the circumference of a wheel of radius = 7.20. The wheel rotates freely about its axis and the string wraps around its circumference without slipping. At first the wheel rotates..
