Question

question 2 of 24. a potted plant falls from the window of an apartment building. it falls for 2.0 s and then hits the ground. what is the speed of the plant just before it hits the ground? assume only gravity is acting on it. a. 20 m/s b. 9.8 m/s c. 4.9 m/s d. 2.0 m/s

Explanation:

Step1: Identify free fall parameters

u=0 m/s, a=9.8 m/s², t=2.0 s

Step2: Apply final velocity formula

v = u + at = 0 + 9.8×2.0 = 19.6 m/s ≈ 20 m/s

Answer:

A. 20 m/s
