You fly 20.0 km in a straight line in still air a direction 40o south of west.
(a) Find the distances you would have to fly straight south and then straight west to arrive at the same point. (This is equivalent to finding the components of the displacement along the south and west directions.)
(b) Find the distances you would have to fly first in a direction 45o south of west and then in a direction 45o west of north. These are the components of the displacement along a different set of axes -- one rotated 45o.
The water is near freezing in temperature. Typically a human can only swim in such water for about 5 minutes before hypothermia sets in. Calculate the time the explorer spends in the water if the river is 87.3 feet wide
A 1.5 kg mass is held at rest on top of a frictionless and horizontal table. A light string loops over a pulley which is in the shape of a 10 cm radius solid disk which has a mass of 1.5 kg. What is the acceleration of the falling mass
A parallel-plate capacitor carries a constant charge Q (i.e., +Q on one plate, and -Q on the other). When a dielectric is inserted between the plates, what happens to the charge on the plates
A body of mass 2.1 kg makes an elastic collision with another body at rest and continues to move in the original direction but by one-fourth of its original speed. What is the mass of the other body? What is the speed of the two-body center of mass i..
you have fixed costs of $608,000 per year. Your tax rate is 31 percent and your required return on this project is 11 percent. Illustrate what bid price per stamp should you submit?
A well-lubricated bicycle wheel spins a long time before stopping. Suppose a wheel initially rotating at 200 rpm takes 62 s to stop. If the angular acceleration is constant, how many revolutionsdoes the wheel make while stopping?
After 1.86 days, the activity of a sample of an unknown type radioactive material has decreased to 88.8% of the initial activity
120-v rms signal at 60.0hz is applied across a 30.0mH inductor and a 100 resistor. what is the rms value of the voltage across the inductor
A spring gun is compressed 30 cm and is held in place by a trigger. The spring mechanism is pushing against a marble of mass 10 grams. What is the maximum height reached by the center of mass of the marble above its initial position before it falls..
A 1.4Kg block and a 2.6kg block are attached to opposite ends of a light rope. what is the acceleration of the lighter block
In a 30.0 s interval, 470 hailstonesstrike a glass window of area 0.600 m2 at an angle of45.0° to the window surface. Each hailstone has a mass of 5.00g and a speed of 8.30 m/s. If thecollisions are elastic, find the pressure on the window.
