Q. What is the magnitude of the acceleration of two falling sky divers (mass = 140 including parachute) when the upward force of air resistance is equal to one-fourth of their weight?
Q. A 16 kg steel ball is launched from a cannon at an angle of 20 degrees above the horizontal. The cannon exerted an average force of 1200 Newtons on the ball during launch. Now that the ball is in the air and has almost reached its target, what is the magnitude of the net force acting on the ball? (Neglect air resistance.)
If the elevator's descending speed is measured at 10 m/s at a given point, but its speed is decreasing by 2.7 m/s2, what is a force exerted by the scale.
what is the new force between the objects. if Andromeda contains roughly the same number of stars and attracts the Milky Way with a gravitational force of 2.4*10^30N.
A box weighing 77.0 N rests on a table. A rope tied to the box runs vertically upward over a pulley and a weight is hung from the other end. Determine the force that the table exert on the box if the weight hanging on the other side of the pulley ..
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.
The height of a helicopter above the ground is given by h = 3.00 t3, where h is in meters and t is in seconds. After 2s, the helicopter releases a small mailbag. How long after its release does the mailbag reach the ground.
At one instant a bicyclist is 43 m due east of a park's flagpole, going due south with a speed of 12 m/s. Then 22 s later, the cyclist is 43 m due north of the flagpole, going due east with a speed of 12 m/s.
A horse canters away from its trainer in a straight line, moving 111 m away in 15.0 s. It then turns abruptly and gallops halfway back in 4.90 s.
Quadrupole moments in the shell model
Two automobiles of equal mass approach an intersection. One vehicle is travelling with velocity 13 m/s toward the east and the other is travelling north with speed v2i. Neither driver sees the other.
At one instant a bicyclist is 49m due east of a park's flagpole, going due south with a speed of 14 m/s. Then 40s later, the cyclist is 49m due north of the flagpole, going due east with a speed of 14m/s. For the cyclist in this 40s interval, what..
Compare the kinetic energy of car travelling. Compare the kinetic energy of an 900 kg car travelling at 30 m/s, and a 1,800 kg car at the same speed.
A Ferris wheel is a vertical, circular amusement ride with radius 6 m. Riders sit on seats that swivel to remain horizontal. The Ferris wheel rotates at the constant rate, going around once in 6.4 s. Consider a rider whose mass is 70 kg.
