If a ball is thrown into the air with a velocity of 52 ft/s, its height in feet t seconds later is given by y = 52t - 16t2. (a) Find the average velocity for the time period beginning when t = 2 and lasting for each of the following. (i) 0.5 seconds ft /s (ii) 0.1 seconds ft/s iii) 0.05 seconds ft/ s (iv) 0.01 seconds ft/s (b) Estimate the instantaneous velocity when t = 2. ft/s Need Help?
