A student drop a 2 kilogram book and 10 kilogram book from a height af 10 meters

Answer 1

The acceleration due to gravity is approximately 9.8 m/s^2. To calculate the final velocity of the books when they hit the ground, we can use the formula:

v = sqrt(2gh)

where:
v = final velocity
g = acceleration due to gravity (9.8 m/s^2)
h = height (10 meters)

For the 2 kilogram book:
v = sqrt(2 * 9.8 * 10)
v = sqrt(196)
v = 14 m/s

For the 10 kilogram book:
v = sqrt(2 * 9.8 * 10)
v = sqrt(196)
v = 14 m/s

So both books will hit the ground at the same final velocity of 14 m/s.
