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.

Question

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.

You want to evaluate y at t = 2.0 and t = 2.5.  The average velocity over this interval will be 1/(0.5) * ( v(2.5) - v(2.0) ) .
