Final answer:
To calculate the time it takes for a body to reach the ground, we can use the equation h = 1/2gt^2, where h is the height and g is the acceleration due to gravity. Simplifying the equation, the time is approximately √(h/5) seconds.
Step-by-step explanation:
The time it takes for a body to reach the ground can be calculated using the equation h = 1/2gt^2, where h is the height and g is the acceleration due to gravity. In this case, g is given as 10 m/s². Let's assume the height is h meters. Plugging the values into the equation, we get:
h = 1/2 * 10 * t^2
Simplifying the equation, we get:
t = √(h/5) seconds
So, the time it takes for the body to reach the ground is approximately √(h/5) seconds.
