I get a. but not sure what went wrong for b. Thank for the help!

11. If the height of an object is determined by the function |h(t) h(t)--4.9t?+ 15t +20where h(t) Lt)" is the height in meters after t seconds a. Determine the average -4130 S Atm velocity on the interval for t of [2, 3]. Estimate the instantaneous pu evahun in cc speed at t-2 using numerical methods. Explain your work. close to 2 on hghe ta side. 1.99 30.1144 II. . | 2 , ooo Show your work and give the units on your answers. 01.730.4 2.oa l 3o.39

Explanation / Answer

h(t)=-4.9t2+15t+20

b.Instantaneous speed, dh/dt=-9.8t+15

at t=2

Speed=-9.8(2)+15=-19.6+15=-4.6flm/sec

And speed have to be positive, so its 4.6m/sec
