A particle of mass 4.12 × 10-27 kg, moving at 4.62 × 105 m/s, strikes an identical particle which is initially at rest. After the interaction, the particles (which can't be distinguished) are observed moving at angles 55.3° and 34.7°, both angles being measured with respect to the original direction of motion. What are the final speeds of the particles? Please provide step-by-step method to get the answer.
A 3.50 x 10^2 N child is in a swing that is attached to ropes 1.75 m long. find the gravitational potential energy associated with the child relative to her lowest postion. What is the net charge inside the die.
A shopper pushes a cart 44- m south down one aisle and then turns 90.0° west and moves 30 m. He then makes another 90° turn and moves 13 m.
A certain airplane has a speed of 250.0 km/h and is diving at an angle of 30.0° below the horizontal when the pilot releases a radar decoy. The horizontal distance between the release point and the point where the decoy strikes the ground is 700 m..
The escape speed from a very small asteroid is only 26 m/s. If you throw a rock away from the asteroid at a speed of 39 m/s, what will be its final speed.
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..
The wheel of a car has a radius of .350 m. the engine of the car applies a torque of 295 Nxm to this wheel that does not slip against the road surface.
Calculate the horizontal force that must be applied to a 1.00 kg puck to make it accelerate on a horizontal friction-free air table with same acceleration it would have if it were dropped and fell freely.
A 12-inch cast iron water pipe that has been in service for 50 years is found to have extensive corrosion inside. How these conditions would affect friction losses in the pipe describe it.
Decide the speed with the rock is thrown
A wave crest passes an observation point followed by a second crest. The time between crest is a period of 168.818 seconds. If the wave is traveling at a speed of 154.167 m/s, how long are the wavelengths?
A screen is placed 1.30 {rm m} behind a single slit. The central maximum in the resulting diffraction pattern on the screen is 1.70 {rm cm} wide-that is, two first-order diffraction minima are separated by 1.70 {rm cm}.
