same way as the other one but here
v = ds/dt = 2 t + 4
so at t = 5
v = 2(5) + 4 = 14 m/s
Suppose that an object moves along an s-axis so that its location is given by s(t)=t^2+4t at time t.(Here is in meters and is in seconds.)
(a) Find the average velocity of the object in meters per second over the time interval t=2 to t=9 seconds.
Average velocity = ? m/s.
(b) Find the instantaneous velocity of the object in meters per second at t=5 seconds.
Instantaneous velocity = ? m/s.
