David can finish painting the room in six hours and his elder brother Anthony can finish it in four hours if both brothers paint
lbvjy [14]

Answer:

2.4 hours

Step-by-step explanation:

David's time = 6 hours

Anthony's time = 4 hours

the combined time is given by the following formula

1/ (david's time) + 1/(anthony's time) = 1/total time

1/6 + 1/4 = 1/Total

4/24 + 6/24 = 1/Total

10/24 = 1/ total   (taking reciprocal of both sides)

24/10 = total

total time = 24/10 = 2.4 hours

A rock is dropped from the top of a building and hits the ground at a velocity of
soldier1979 [14.2K]

The height of the building comes to be 81 feet.

Initial velocity u= 0 feet/sec

Final velocity v= 72 feet/sec

The acceleration due to gravity g =32ft /sec²

Height of the building h= suppose h

<h3>What is the equation of motion?</h3>

The equation of a motion is:

v^{2} =u^{2} +2gh

Where u and v are the initial and final velocities.

72^{2} =0+2*32*h\\144 = 64h\\h=81

So, the height of the building = 81 feet.

Therefore, the height of the building comes to be 81 feet.
