Question

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

Answer 1

Answer:

She traveled 70560 m.

Step-by-step explanation:

Given :

Acceleration (g) =   $-9.8m/s^{2}$

Time : 120 seconds .

To Find : Distance traveled

Solution:

Since we are given that there is a free fall .

So, we will use the formula:   $d=\frac{1}{2} gt^{2}$

Now put the given values in the formula :

⇒$d=\frac{1}{2}*(-9.8)*(120)^{2}$

⇒$d=\frac{1}{2}*(-9.8)*14400$

⇒$d=\frac{-141120}{2}$

⇒$d=-70560$

Negative sign shows the direction only.

Hence she traveled 70560 m.
