Desde una azotea de un rascacielos de 120 m. de altura se lanza una piedra con velocidad de 5 m/s , hacia abajo. Calcular a) Tiempo que tarda en llegar al suelo, b) velocidad con que choca contra el suelo

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

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.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
