Two forces are applied to a car in an effort to move it, as shown in the following figure, where F1 = 446 N and F2 = 399 N. (Assume up and to the right as positive directions.)
a) What is the resultant of these two magnitudes?
b) What is the direction to the right of the forward direction?
Suppose a cylindrical habitat in space 5.90 km in diameter and 37.0 km long has been proposed. How fast would the cylinder have to rotate to imitate the Earth's gravitational field at the walls of the cylinder
A 0.54-kg particle has a speed of 2.0 m/s at point A and kinetic energy of 7.5 J at point B. What is its speed at point b
A container of volume 23 cm3 is initially filled with air. The container is after that evacuated at 0oC to a pressure of 30 mPa. How many molecules are in the container after evacuation if we suppose that air is an ideal gas.
To stretch a certain spring by 2.70 cm from its equilibrium position requires 7.00 J of work. What was the maximum force required to stretch it by that distance
A sailor strikes the side of his ship just below the waterline. He hears the echo of the sound reflected from the ocean floor directly below 1.3 s later. How deep is the ocean at this point? Suppose the speed of sound in seawater is 1560 m/s and d..
