A day on a distant planet observed orbiting a nearby star is 31.7 hours. Also, a year on the planet lasts 79.5 Earth days.* Calculate the average angular speed of the planet about its own axis of rotation in radians per second, with the second as measured on Earth.
Calculate the average angular speed of the planet as it travels around its neighboring star, with the second as measured on Earth.
If the coefficient of static friction is 0.951, illustrate what is the maximum speed that the car can take without skidding?
A 55-kg swimmer is standing on a stationary 210-kg floating raft. The swimmer then runs off the raft horizontally with a velocity of +4.6 meter per second relative to the shore. Calculate the recoil velocity that the raft would have if there were ..
how long does it take to reach the new equilibrium position.
A 7.90×10-2-{rm kg} toy airplane is tied to the ceiling with a string. While the airplane's motor is started, it moves with a constant speed of 1.20m/s in a horizontal circle of radius 0.50m.
A circuit consists of a battery connected to three resistors (65?, 26?, and 170?) in parallel. find the current through each resistor
A 6.00 g bullet is fired horizontally at two blocks resting on a smooth tabletop, as shown in the top figure, find the speed of the bullet immediately after it emerges from the first block, find the bullet's original speed
A car of mass 1,250 kg is lowered onto a junk pile at the end of the cable of a large crane. If the car is accelerating downward at 0.19 m/s2
The indices of refraction for violet light (? = 400 nm) and red light (? = 700 nm) in diamond are 2.46 and 2.41, Calculate the angular separation between these two colors of light in the refracted ray
A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. What is the amplitude A of each wave
compare with the force of gravitational attraction between them.Find the position of the particle after this time.
A damping force acts on the egg, and the amplitude of the motion decreases to 0.101 in a time of 5.00 compute the magnitude of the damping constant b.
At its Ames Research Center, NASA uses its large "20-G" centrifuge to test the effects of very large accelerations (hypergravity) on test pilots and astronauts. In this device, an arm 8.84m long rotates about one end in a horizontal plane, and the..
