An air cyclone is used to separate solid particles having different masses. The cyclone radius is 0.8 meter and its rotational velocity is 100 revolutions per minute. Determine the centrifugal acceleration of the particles?
A golf ball of mass 0.045 kg is hit off the tee at a speed of 35m/s . The golf club was in contact with the ball for 3.90×10?3s. Find the impulse imparted to the golf ball
A particle has a charge of q = +5.2 µC and is located at the origin. As the drawing shows, an electric field of Ex = +229 N/C exists along the +x axis. A magnetic field also exists, and its x and y components are Bx = +1.7 T and By = +1.3 T.
A 779-kg car stopped at an intersection is rear-ended by a 1820-kg truck moving with a speed of 15.0 m/s. If the car was in neutral and its brakes were off, so that the collision is approximately elastic, find out the final speed of both vehicles ..
