Question

A body fall from a height of 45 m from the ground. Find the time taken by the body to reach the ground(g= 10m/s^2

Answer 1

Answer:

Take the square root of the result to calculate the time it takes for the object to drop. For example, the square root of 1.02 s^2 equals 1.01 s. Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground.How to use the free fall formula: an example

Determine the gravitational acceleration. ...

Decide whether the object has an initial velocity. ...

Choose how long the object is falling. ...

Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + g * t = 0 + 9.80665 * 8 = 78.45 m/s .
