How long would it take for a ball dropped from the top of a 100-foot building to hit the ground? Round your answer to two decimal places.

time = 2.48 seconds

Step-by-step explanation:

Given data:

distance = 100 foot

Initial velocity = 0 because it was held and being released.

acceleration is gravitational force

gravitational force in feet per second = 32.2 ft/s²

formula for distance is s = ut +(1/2)at² where s = distance , u = intial velocity , a = acceleration and t = time

s = ut +(1/2)at²

100 = 0(t) + (1/2)(32.2)t²

100 = 16.2t²

100/16.2  = t²

therefore t = 2.484

t = 2.48 seconds (to 2 decimal places)

they disappear if your absent from to long. i found out that the hard way.

brainliest lol i just need one more brainliest.

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
