The height after 6 seconds is 190

What is the velocity after 6 seconds?

**Reiny**, Friday, January 25, 2013 at 6:28pmh(6) = 100+45(6) - 5(36) = 190 m

Wow, this person was able to throw a rock upwards 90 m, the height of roughly a football field ??

velocity = h' (t) = 45 - 10t

when t=6

velocity = 45 - 60 = -15 m/sec
