Question

Suppose air resistance does not exist, roughly what would be the velocity of a 10 lb object 5-seconds into free fall off of a 500-m building? How is this answer 50 m/s?

Answer 1

Answer:

Correct answer :  v = 50 m/s

Explanation:

The movement described is a free fall with no initial velocity and we will use the following formula:

v = g · t   we take that g = 10 m/s²

v = 10 m/s²· 5 s = 50 m/s

v = 50 m/s
