A proton with an initial velocity of (1.0x + 2.0y + 3.0z) × 105 m/s enters a magnetic field of 0.50z T. Find the force on the proton. The mass of the proton is 1.67 × 10-27 kg. Wherex,y andz are unit vectors in the x, y and z directions, respectively.
A slingshot fires a pebble from the top of a building at a speed of 14.0m/s. The building is 31.0 m tall. Ignoring air resistance, find the speed with which the pebble strikes the ground when the pebble is fired horizontally.
