Question

At a construction site a wrench strikes the ground with a speed of 24.0 m/s. a) from what height was it dropped? b) for how long was it falling?

Answer 1

Step-by-step explanation:

vf = vo + at

24 = 0 + 9.81 t

t = 2. 45 s

d = do + vo t + 1/2 a t^2

0 = do + 0 *t + 1/2 (-9.81 )(2.45)^2

do = 29.4 m
