1-Para cubrir su ruta por la ciudad un autobús se desplaza 5 km hacia el oeste, dobla hacia la izquierda y recorre 3 km, da vuelta hacia el este y avanza 10 km, luego se dirige al norte y recorre
5 km, de nuevo viaja hacia el este 5 km y finalmente se desplaza 2 km hacia el sur. Indiquen: ¿Qué
distancia recorrió? ¿cuál fue el vector desplazamiento y su módulo?

Need only answer if you think you know it

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.

Agirl throws a ball. if the ball's acceleration is 12 m/sec/sec and its mass is 0.5 kg, how much force did the girl apply to the ball?
