**Damon**, Monday, July 25, 2011 at 7:54pmVi = -64 m/s (velocity is down)

dv/dt = a = +7m/s^2 (acceleration is up)

h = hi + Vi t + (1/2) a t^2

h - hi = -64(10) + 3.5 (100)

= -640 + 350

= - 290

so it went down 290 meters

**Damon**, Monday, July 25, 2011 at 10:30pmh = hi + Vi t + (1/2) a t^2

usually

x = Xi + Vi t + (1/2) a t^2

**Anonymous**, Friday, July 29, 2011 at 11:51amIn first one second it descends 64 m ,

Next one second it descends =(64-7)=57 m

Then next one second it descends = ( 57-7)=50 m,

4th second it descends =50-7=43 m

5th second it descends = 43-7=36 m.

6th second it descends = 36-7=29 m.

7th second it descends = 29- 7= 22 m

8th second it descends = 22-7=15 m

9th second it descends = 15-7=8 m.

10th second it descends = 8-7=1 m

Total distance covered by it= 64+57+50+43+36+29+22+15+8+1= 325 m
