Answer:

Explanation:

a. To find the time it takes for the stone to hit the floor, we can use the formula t = sqrt(2h/g), where h is the height of the table and g is the acceleration due to gravity. Plugging in the values, we get:

t = sqrt(2(1.5 m)/9.8 m/s^2) = 0.55 seconds.

b. To find the horizontal distance traveled by the stone, we can use the formula d = vt, where v is the initial velocity of the stone and t is the time it takes to hit the floor. Plugging in the values, we get:

d = (0.80 m/s) * (0.55 s) = 0.44 meters.

Therefore, the stone will hit the floor after 0.55 seconds and will travel 0.44 meters from the table.
