If a ball is thrown in the air with a velocity 50 ft/s, its height in feet t seconds later is given by y = 50t - 16t2. (Round your answers to one decimal place.)

Find the average velocity for the time period beginning when t = 2 and lasting 0.5 second.

jdoe0001 · Answer

so, the average velocity will be given in $\bf \cfrac{feet}{sec}$  that is in $\bf \cfrac{y}{x}$

so, you'd want the value of  "y", at x=0.5 and at x = 2 
then get the average between both fractions
