Leticia leaves the grocery store and walks 150.0m to the parking lot. Then, she turns 90 degrees to the right and walks an additional 70.0m to her car. What is the magnitude of the displacement of her car from the grocery store exit? Round your answer to the nearest tenth

Aproton is projected into a uniform electric field that points vertically upward and has magnitude e. the initial velocity of the proton has a magnitude v0 and is directed at an angle a below the horizontal. (a) find the maximum distance hmax that the proton descends vertically below its initial elevation. you can ignore gravitational forces. (b) after what horizontal distance d does the proton return to its original elevation? (c) sketch the trajectory of the proton. (d) find the numerical values of hmax and dife = 500 n> c,v0 = 4.00 * 105 m> s,anda = 30.0°.
