A proton moves at 5.40 E5 m/s in the horizontal direction. It enters a uniform vertical electric field with a magnitude of 9.40 E3 N/C. Ignore any gravitational effects.
(a) Find the time interval required for the proton to travel 6.00 cm horizontally. [ns]
(b) Find its vertical displacement during the time interval in which it travels 6.00 cm horizontally. (Indicate direction with the sign of your answer.) [mm]
(c) Find the horizontal and vertical components of its velocity after it has traveled 6.00 cm horizontally. [ (i) and (j) components km/s]
A proton is projected in the positive x direction into a region of uniform electric field = (-5.20E5) N/C at t = 0. The proton travels 6.20 cm as it comes to rest.
(a) Determine the acceleration of the proton. [magnitude m/s2]
(b) Determine the initial speed of the proton. [magnitude m/s]
(c) Determine the time interval over which the proton comes to rest. [s]
A model car is propelled by a cylinder of carbon dioxide gas. The cylinder emits gas at a speed of 4.5 g/s with an exit speed of 80.0 m/s. The car has a mass of 400 g, including the CO2 cylinder. Starting from rest, what is the car's initial accel..
A force with a magnitude of 452N is used to bring an object with a mass of 56.0 kg moving at a velocity of 155m/s. How long will it take to bring the object to a full stop.
Assume that a 16.5 m/s wind is blowing across the roof of your house. The density of air is 1.29 kg/m3. Conclude the reduction in pressure (below atmospheric pressure of stationary air) that accompanies this wind.
