A boat has a mass of 5220 kg. Its engines generate a drive force of 4480 N due west, while the wind exerts a force of 730 N due east and the water exerts a resistive force of 1880 N due east. Take west to be the positive direction. What is the boat's acceleration, with correct sign?
Find the position of the object to acquire real, magnified image, inverted, and virtual, upright image.
Dan is gliding on his skateboard at 2m/s. He suddenly jumps backward off the skateboard, kicking the skateboard forward at 7.00m/s (as measured by an observer on the ground). Dan's mass is 50 kg and the skateboard's mass is 5.00 kg.
A rotating cylinder about 18km in length and 6km in diameter is designed to be used as a space colony. With what angular speed must it rotate so that residents on it will experience the same acceleration because of gravity on Earth.
A satellite revolves around a planet at an altitude equal to the radius of the planet. The force of gravitational interaction between the satellite and the planet is F_0. Then the satellite moves to a different orbit, so that its altitude is tripl..
An adult exerts a horizontal force on a sewing that is suspended by a rope of length L, holding it at an angle x with the vertical. The child in the swing has a weight W and dimensions that are negligible compared to L.
A Michelson interferometer uses light from glowing hydrogen at 486.1 nm. As you move one mirror, 530 bright fringes pass a fixed point in the viewer. How far did the mirror move.
If unpolarized light of intensity l0 passes through an ideal polarizer, what is the intensity of the emering light
Two children setup a "telephone" by placing a long, slender aluminium (Y = 6.9 × 1010 N/m2) bar that has a length of 6.1-m between their two houses. To communicate, the child taps a coded message on one end. How long do the sound waves take to reach ..
