Question

PLEASE HELP ASAP!!!!!!!!!!!!

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.)

Answer 1

a = acceleration of swati during free fall = - 9.8 meter/second²

v₀ = initial velocity of swati = 0 meter/second

t = time of travel = 120 seconds

d = displacement of swati during free fall

Using the kinematics equation

d = v₀ t + (0.5) a t²

inserting the values

d = (0) (120) + (0.5) (- 9.8) (120)²

d = - 70560 m

hence distance travelled by swati is 70560 m
