An electron with initial velocity vo = 1.61 x 105 m/s enters a region 1.00 cm long where it is electrically accelerated (see the figure). It emerges with velocity v = 5.66 x 105 m/s. What is its acceleration, assumed constant? (Such a process occurs in old television sets.) Nonaccelerating Accelerating region region Path of electron Source of high voltage Number UnitsA car is driven east for a distance of49 km, then north for 23 km, and then in a direction 29" east of north for 22 km. Determine {a} the magnitude of the car's total displacementtrom its starting point and {b} the angle {from east) of the car's total displacement measured from its starting direction.
