Una bicicleta se desplaza con una rapidéz de 10m/s donde sus ruedas tienen un diametro de 60cm el ciclista comienza a frenar uniformemente y se detiene en 40s.
-calcular que distancia recorrió en ese tiempo, con que desesaleración angular frenó, cuantas vueltas dieron las ruedas hasta detenerse.

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
