A ball of mass 0.300kg that is moving with a speed of 5.4m/s collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.9m/s .
1) Calculate the velocity of the target ball after the collision.
2) Calculate the mass of the target ball.
A loudspeaker of mass 19.0 kg is suspended a distance of h = 2.00m below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l= 3.50m. Illustrate what is the tension T in each of the cables?
Find out the magnitude of that push.
Boxes are transported from one location to another in the ware-house by means of a conveyor belt that moves with a constant speed of 0.50m/s. At a certain location the conveyor belt moves for 2.00 m up an incline that makes an angle of 10° with the h..
Find out the sum of these four vector forces: 12N to the right at 35.0° above the horizontal, 31.0 N to the left at 51.5° above the horizontal, 7.45N to the left at 35.0° below the horizontal, and 24N to the right at 48.0° below the horizontal.
Let the building is 50 m tall, the initial horizontal velocity is 9.0 m/s, and the initial vertical velocity is 12.0 m/s. select your coordinates such that the positive y-axis is upward, and the x-axis is to the right, and the origin is at the poi..
A 13 g bullet traveling 215m/s penetrates a 2 kg block of wood and emerges cleanly at 157m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after bullet emerges.
what is the electric potential energy of this particle. what is its speed just before it strikes the positive plate.
A toy car moves at a velocity of 65.00 m/s on a compass heading of 115degrees. What are the components, magnitude and direction of car.
The 60kg cradle A is carrying the 12 kg pipe B at the speed of 8 m/s when it hits the rigid wall. suppose all the impacts are plastic, determine the speed of the pipe immediately after the impacts. Neglect friction.
A tennis ball is thrown toward a vertical wall with a speed of 22.0 m/s at the angle of 40.0° above the horizontal. The horizontal distance between the wall and the point where the tennis ball is released is 28.0 m.
A helicopter flies at a constant altitude towing a mass M of 119 kg. The helicopter and the mass have a horizontal acceleration of 2.54 m/s^2. Ignore air resistance find the tension in the cable.
Two adjacent natural frequencies of an organ pipe are determined to be 299 Hz and 345 Hz. (Suppose the speed of sound is 343 m/s.)
