Q1. The French train is travelling at 305 km/h. When it is 350 m from a road crossing, it blows the whistle. If speed of light is 335 m/s, how many seconds after the whistle is heard at the crossing will the train cross there?
Q2. A 1.5 {rm kg} block rests on top of a 7.5 {rm kg} block. The cord and pulley have negligible mass, and there is no significant friction anywhere. What force F should be applied to bottom block so the top block accelerates to the right at 2.60 m/s^2?
What is the acceleration in m/s of a 0.001kg bullet if the force of recoil gives an acceleration of 4.390 m/s? The gun has mass of 0.20 kg.
Two trains, each having a speed of 28 km/h, are headed at each other on the similar straight track. A bird that can fly 56 km/h flies off the front of one train, when they are 66 km apart and heads directly for the other train. On reaching the other ..
A sailboat is running along a straight course with the wind providing a constant force of 55 lb. The only other force acting on the boat is resistance as the boat moves through the water. The resisting force is numerically equal to five times the boa..
Next you eliminate the 11 kg mass, place the rod horizontally, and strike one end with a hammer. How much time t would elapse before a microphone at the other end of the bar will detect a disturbance.
A space station, in the form of a wheel 133 m in diameter, rotates to provide an "artificial gravity" of 2.20 m/s2 for persons who walk around on the inner wall of the outer rim. Find the rate of the wheel's rotation in revolutions per minute that wi..
An alpha particle (m = 6.7 x 10^-27kg, q = +3.2 x 10^-19C) has a speed of 30km/s at point A and moves to point B where it momentarily stops. Only electric forces act on the particle throughout this motion. Find out the electric potential difference.
How close to the edge of the 28.0 kg table, that is 2.2m with legs 1.2m apart, can a 62.0 kg person sit without tipping it over.
A diffraction grating with 395 lines/mm is 1.00 m in front of a screen. What is the wavelength of light whose first-order maxima will be 16.9 cm from the central maximum on the screen.
A 220 g air-track glider is attached to a spring. The glider is pushed in 12cm against the spring, and then released. A student with a stopwatch finds that 16 oscillations take 11.5.
How much work is completed on the box by the applied force
