Desde la azotea de un edificio de 27m de altura, se lanza verticalmente y haci arriba una piedra con una velocidad de 30m/s. Calcular: a) velocidad a los 2s, b) altura a los 2 segundos, c) velocidad a los 5s, d) altura los 5s, e) en cuánto tiempo llega al suelo.​

answer: decibel

explanation:

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j

490 n

f=125n a=2.5m/s2
