A singly ionized (one electron removed) 40 K atom passes through a velocity selector consisting of uniform perpendicular electric and magnetic fields. The selector is adjusted to allow ions having a speed of 4.50 km/s to pass through undefiected when the magnetic field is 0.0250 T. The ions next enter a second uniform magnetic field ( B ') oriented at right angles to their velocity. 40 K contains 19 protons and 21 neutrons and has a mass of 6.64 × 10 −26 kg. (a) What is the magnitude of the electric field in the velocity selector? (b) What must be the magnitude of B' so that the ions will be bent into a semicircle of radius 12.5 cm?

A shot putter releases a shot at 13 m/s at an angle of 42 degrees to the horizontal and from a height of 1.83 m above the ground. Calculate. Note: For each question draw a diagram to show the vector/s. Show all the steps and provide units in the answers. Provide answer to 2 decimal places unless stated otherwise. Answer all parts and show all work please.
A player kicks a football at the start of the game. After a 4 second flight, the ball touches the ground 50 m from the kicking tee. Assume air resistance is negligible and the take-off and landing height are the same (i.e., time to peak = time to fall = ½ total flight time). Calculate: Note: For each question draw a diagram to show the vector/s. Show all the step and provide units in the answers. Provide answer to 2 decimal places unless stated otherwise.)
