Question

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

Please dont just tell me the answer i would like to learn how to do the problem

Answer 1

d = (1/2)at^2

"a" is the acceleration, which is only g in this case so
t is the time, which we are given (120 seconds)

so plugging them in gives us

d = (1/2)(-9.8)(120^2)

Answer 2

this will give you a negative answer because the acceleration is in the downward direction. however they are asking about distance so you would just report the absolute value (just knock off the negative sign)
