h and g are same for both the balls, so time of fall ‘t’ will also be the same for both of them (h is vertical height]

a) How long does it take for stone A to hit the ground?
Using the equation for free fall:
h = (1/2)gt^2
where h is the initial height (10 m), g is the acceleration due to gravity (-9.8 m/s^2), and t is the time it takes for the stone to hit the ground.
Plugging in the values, we get:
10 = (1/2)(-9.8)t^2
Simplifying:
t^2 = 2(10)/9.8
t^2 = 2.04
Taking the square root of both sides:
t = 1.43 seconds
Therefore, it takes stone A 1.43 seconds to hit the ground.
b) How far away from the building does stone B land?
Since stone B is thrown horizontally with an initial speed of 5 m/s, its horizontal motion is described by:
x = vt
where x is the distance traveled, v is the initial velocity (5 m/s), and t is the time it takes to travel that distance.
The time it takes for stone B to hit the ground is the same as the time it takes for stone A, which we found to be 1.43 seconds.
Therefore:
x = (5 m/s)(1.43 s)
x = 7.15 meters
Stone B lands 7.15 meters away from the building.
