A proton is located at a distance of 0.435 m from a point charge of +8.46 μC. The repulsive electric force moves the proton until it is at a distance of 1.80 m from the charge. Assume that the electric potential energy lost with the system is carried off by a photon that is emitted through the process. What is its wavelength?

A basketball (M = 0.6 kg, R = 12.1 cm) with a tennis ball (m = 0.06 kg, r = 3.25 cm) directly on top of it is dropped from a height of 1 m. Find the speed of the basketball after its collision with the ground
As the drawing shows, the bullet puts a hole in a window of another building and hits the wall that faces the window. h is 0.54 m and d is 8.0 m. Assume that the bullet does not slow down as it passes through the window. Evaluate the Distance H
A spacecraft is traveling with a velocity of vox = 5675 m/salong the +x direction. Two engines are turned on for a time of 847 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 1.25 m/s2,while the other gives it an acc..
