Ga proton moves at 3.60 105 m/s in the horizontal direction. it enters a uniform vertical electric field with a magnitude of 9.40 103 n/c. ignore any gravitational effects. (a) find the time interval required for the proton to travel 4.00 cm horizontally. ns (b) find its vertical displacement during the time interval in which it travels 4.00 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 4.00 cm horizontally.

Which accurately compares concave and convex lenses?

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
