To find the velocity with which the sheet of paper hits the ground, we can use the laws of motion. The equation we can use in this case is the second equation of motion, which relates displacement, initial velocity, final velocity, and acceleration:

v^2 = u^2 + 2as

Where:
- v is the final velocity
- u is the initial velocity (which is 0 since the paper is dropped)
- a is the acceleration due to gravity (approximately 9.8 m/s^2)
- s is the displacement

In this case, the displacement (s) is the height from which the paper is dropped, which is 5m. Substituting these values into the equation, we get:

v^2 = 0 + 2(9.8)(5)
v^2 = 0 + 98
v^2 = 98

Taking the square root of both sides, we find:

v = sqrt(98)
v ≈ 9.90 m/s

Therefore, the velocity with which the sheet of paper hits the ground is approximately 9.90 m/s.
