Question

What is the velocity of an object after falling for 15 seconds, neglecting air resistance? (g=9.81)
O 77.499
O 0.64m/s^2
O 15.53 m/s to the left.
147.15 m/s downward.

Answer 1

Answer:

(ans147.15m/s downward)

Explanation:

initial velocity (u)=0m/s

final velocity (v)=?

v=u+gt. ( t)time taken=15seconds

?=0+(9.81)×15

?=147.15m/s

hope this helped
