How far does a freely falling body travel during the fourth second of

its fall?



Answer: 34.3m



Please and thank you!!How far does a freely falling body travel during the fourth second of?The distance a body falls as a function of time is:

d = 陆gt虏, where g = 9.8 m/s虏.

The "fourth second" is from time t = 3 seconds to t = 4 seconds, so the distance covered during that time interval is:

d = 陆 (9.8 m/s虏) (4 s)虏 - 陆 (9.8 m/s虏) (3 s)虏 = 34.3 m.How far does a freely falling body travel during the fourth second of?34.3m
