Question:

Free fall physics question: a construction worker accidentally drops a brick from a high scaffold..?

A) what is the velocity of the brick after 4.0 s?B) how far does the brick fall during this time? This is using 9.8 m/s^2 as the acceleration

Answer:

v = a*t d = (1/)at^2 Plug in the numbers.
Sony are you ultimately seeing the real image right here,LOL? definite it does stress wages down.For the two electorate and non. this is the large factor approximately slave hard artwork.poor human beings are SOOO lots much less complicated to regulate than wealthy or perhaps people who do no longer would desire to count on government advantages uld you talk out against our government in case you depended on them to consume that day?No you will not.we want a majority of poor in accordance to the government.So we import slave hard artwork to stress wages down.do no longer hate the gamers of the interest Sony hate the interest makers.they're those you're able to be yelling approximately.
Since acceleration is constant which is 9.8 m/s^2, the velocity increases by the fixed 9.8 amount every second, so: A) v = v0 + gt = 0 + 9.8*4 = 39.2 m/s where v0 is initial speed which in this case is zero. B) We use constant acceleration equation: x = x0 + v0*t + 1/2gt^2 = 1/2 gt^2 = 1/2 *9.8 * 16 = 8*9.8 = 80 - 1.6 = 78.4 m
