Use the formulav^2 = u^2 + 2*a*swhere v is the final velocity of the ballu is the initial velocity of the balls is the displacement of the balla is the acceleration 
Givenv=130u=0s=0.1a=?
130^2 = 0^2 + 2a(0.1)solve for a
a = 84500 m/s2

How and why does breathing rate increase during exercise
kondor19780726 [428]

When a fit person, such as an athlete, exercises the pulse rate, breathing rate and lactic acid levels rise much less than they do in an unfit person.
