You  throw a golf ball off of the top of a building  that is 14 m above the    ground. The    ball is initially  thrown  12m/s  horizontally.    a)How  long does it take for the ball to hit the ground? b) How far away from the base of the building does the ball hit the ground?   

explanation:

the masses of the objects and the distance between them

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
