PLEASE HELP PHYSICS/MATH??
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. (Do not forget to keep units in your answer.)

Histrionicus

Given: Acceleration (a) = 9.8 m/s², Initial velocity (u) = 0 m/s and time (t) = 120 s

To find: The distance traveled by Swati (s) =?

Solution: We shall apply 2nd kinematic equation of motion

                        s = ut + (1/2) at²

or,                     s = 0×120 +  (1/2) × (9.8 m/s²) × (120s)²

or,                     s = 70,560 m

or,                     s = 7 km and 560 m

Hence, the required distance travel by her will be 7 km and 560 m.
