Abrick is dropped from the roof of a tall building. after it has been falling for a few seconds, it falls 47.0 m in a 1.00-s time interval. what distance will it fall during the next 1.00 s? ignore air resistance.

The brick falls with an average speed of 47m/s during 1 second interval

As the acceleration is constant, this will be our reference value at t = 0.5 s, so

lets calculate the value at the end of the interval

Vend_interval = Vinitial + g*(0.5s) = 47[m/s] +9.8(0.5)[m/s] =51.9[m/s]

With this speed we can calculate the distance traveled with the following expression

d = Vinitial*t + 1/2 * g*(t**2)

after 1 second t = 1s

d  = 51.9 [m/s] + 4.9 [m/s] = 56.8 [m]  (new distance traveled after one second)

The correct answer is c

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
