In the diagram below, a particle with mass m = 0.80 g and charge q time t=0, at angle = 65° above the +x direction. The initial speed of the charge is 150 m/s. The charge is subject to a constant electric field E= E). Ignore other forces that might be acting on the charge. As shown in the figure, the charge just barely clears an obstacle 20.0 cm tall. (a) Starting from basic kinematic equations you learned in Physics 1A (or an equivalent course) determine the acceleration of the charge. Remember to work symbolically, and substitute numerical values only at the end of the calddation. (b) What is Ey? (c) At what time t, between launch and the particle going over the obstacle, is the particle moving the slowest? 0 30.0 cm X
