Older televisions display a picture using a device called a cathode ray tube, where electrons are emitted at high speed and collide with a phosphorescent surface, causing light to be emitted. the paths of the electrons are altered by magnetic fields. consider one such electron that is emitted with an initial velocity of 2.20 107 m/s in the horizontal direction when magnetic forces deflect the electron with a vertically upward acceleration of 5.60 1015 m/s2. the phosphorescent screen is a horizontal distance of 6.1 cm away from the point where the electron is emitted. (a) how much time does the electron take to travel from the emission point to the screen? s (b) how far does the electron travel vertically before it hits the screen?

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
