A mango fruit drops from the top of it's tree which is 40 m. How long does it takes to reach the ground
h = 1/2 g t^2
40 = 1/2 * 9.8 * t^2
To calculate the time it takes for the mango fruit to reach the ground, we can use the equation of motion:
Distance = 1/2 * acceleration * time^2
In this case, the distance is 40 m (the height of the tree) and we can assume the acceleration due to gravity is approximately 9.8 m/s^2.
40 = 1/2 * 9.8 * time^2
Now we need to solve for time. Rearranging the equation:
time^2 = (2 * distance) / acceleration
time^2 = (2 * 40) / 9.8
time^2 = 80 / 9.8
Taking the square root of both sides:
time = √(80 / 9.8)
time ≈ 4.04 seconds
Therefore, it takes approximately 4.04 seconds for the mango fruit to reach the ground.
