If a ball is thrown straight up into the air with an initial velocity of 45 ft/s, it’s height in feet after t second is given by y = 45t – 16t^2

a] find the average velocity for the time period begining when t = 2 and lasting.

i) 0.1 seconds

ii) 0.001 seconds

iii) 0.0001 seconds

b) Estimate the instantaneous velocity of the ball when t = 2

averagevelocity for the time period beginning when t = 2 and lasting is: -19.016 ft/sec. Theinstantaneousvelocity of the ball when t = 2 is: 19 ft/sec.## Average velocity
