Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 1 s. What is your acceleration?

Question

mangotangochick · Answer

a = (v-u)/t

a=(13-7)/1

Therefore your acceleration would be 6m/s^-2

mangotangochick · Answer

Whoops sorry I mean 6ms^-2

osprey · Answer

13m/s-6m/s=7m/s. That in 1 sec is 7m/s/s That's SOME big acceleration - gravity is 10m/s/s ! http://perendis.webs.com

13m/s is not exactly walking pace. That's 47 km/h. Probably faster than Usain Bolt can run at full speed.

mangotangochick · Answer

Usain Bolt top speed: (According to Google :)) 
44.64kmh = 12.40ms 

Just about faster than Usain ;)
