Two submarines are moving towards each other in a portion of the Atlantic Ocean where the water is calm. Sub A is moving at 14.0 m/s and sub B is moving at 19.5 m/s. Sub A sends out a sound wave at 1.000 kHz and the speed of sound in the water is 1521 m/s.
(a) What frequency does sub B detect?
(b) What frequency is detected by sub A of the sound reflected from sub B? {1022 Hz, 1045 Hz}
Blocks A and B are connected across a frictionless pulley by a cord of negligible weight. If block B lies on a horizontal, frictionless surface and block A hangs vertically, what can be said about the acceelration of block B?
A bullet is fired through a board 10.0 cm thick in such a way that the bullet's line of motion is perpendicular to the face of the board. The initial speed of the bullet is 400 m/s and it emerges from the other side of the board with a speed of 30..
Julie drives 100 mi to her Grandmother's house. On the way to Grandmother's, Julie drives half the distance at 25mph and the other half at 80. On her return trip, she drives half time at 25mph and half the time at 80 mph.
A bus is traveling up a hill at a speed of 34m/s. The hill is 23 degrees relative to horizontal and the coefficient of static friction between the bus's tires and the road is 0.6. What is the car's minimum breaking distance?
What is maximal speed v of the elevator

When an 82.0-kg adult uses a spiral staircase to climb to the second floor of his house, his gravitational potential energy increases by 2 x 10^3 J. By how much does the potential energy of a 17 kg child increase when the child climbs a normal sta..
A woman stands on a scale in a moving elevator. Her mass is 60.9 kg, and the combined mass of the elevator and scale is an additional 819 kg. Starting from rest, the elevator accelerates upward. Through the acceleration, the hoisting cable applies a ..
An airplane flies due south at 155km/h relative to the air. There is a wind blowing at 89 km/h to the east proportionate to the ground. What are the plane's speed and direction relative to the ground.
A 0.840-kg block oscillates on the end of a spring whose spring constant is k= 42.0 N/m . The mass moves in a fluid which offers a resistive force F=-bv, where b = 0.640 N*s/m. What is the fractional decrease in amplitude per cycle?
Assume we have an infinitely long wire carrying a current of 4.0 A. It is bent into an L-shape extending into positive infinities along the x- and y- axes. Find out the magnitude of the magnetic field at the point P with coordinates (0.2 m, 0.2 m)..
