In a particular x-ray tube, an electron approaches the target moving at 1.10 108 m/s. It slows down on being deflected by a nucleus of the target, emitting a photon of energy 30.0 keV. Ignoring the nuclear recoil, but not relativity, compute the final speed of the electron.
Find a relation between the variables that would guarantee that the block is initially slowing down.
A hockey stick is swung with an average angular acceleration of 1.5 rad/s2. What is an angular velocity of the stick when it strikes the ball at the end of 0.8 second swing.
What is the magnitude of the force applied throughout this time? What is the direction of the force applied throughout this time?
A car drives west on sw 8th street at a speed of 30.7 mph. The driver hits the brakes and the car slows down with a constant acceleration of 4.8 m/s^2
A worker pushes horizontally on a large crate with a force of 297 N, and the crate is moved 4.8 m. How much work was done.
A fully loaded station wagon has a mass of 1690 kg. If each of its four tires is inflated to a gauge pressure of 211 kPa, what is the total tire area in contact with road.
Two vectors A and B have the similar magnitude of 100 N (they represent forces of equal strength). What is the magnitude of the resultant vector of A and B if they are parallel and pointing in opposite directions.
A machine in the factory needs 38 V to operate. The power in the factory is different from that, what is the voltage of the electrical power system in the factory
