Previous Next If a ball is thrown straight up into the air with an initial velocity of 100 ft/s, its height in feet after t seconds is given by y = 100t – 16t2. Find the average velocity for the time period beginning when t= 2 and lasting (i) 0.5 seconds: (ii) 0.1 seconds: (iii) 0.01 seconds: (iv) 0.0001 seconds: Finally, based on the above results, guess what the instantaneous velocity of the ball is when t= 2.

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
