Question

During a free fall Swati was accelerating at -9.8m/s2. After 120 seconds how far did she travel? Use the formula =1/2 * t2 to solve your answer

Answer 1

It is given that the acceleration due to gravity is
`g=-9.8m/s^2`

We know that the formula for the distance of a falling object is given as:

Distance=
`-(1)/(2)* g* t^2` Where the negative sign depicts just the fall from up to down.

Therefore, after 120 seconds the distance Swati will travel is given as:

`Distance=-(1)/(2)* 9.8* 120^2=70560` meters

This is equivalent to 70.56 kilometers.
