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 * t^2 to solve your answer. (Do not forget to keep units in your answer.)

Answer 1

70560 m

Step-by-step explanation:

The formula to calculate the distance travelled during a free fall motion is

`d=-(1)/(2)gt^2`

where

d is the distance travelled

g = -9.8 m/s^2 is the acceleration due to gravity

t is the time

In this situation,

t = 120 s

Therefore the distance travelled after 120 s is

`d=-(1)/(2)(-9.8)(120)^2=70560 m`
