PLZ Help! A stone is tossed into the air from ground level with an initial velocity of 15 m/sec . Its height in meters at time t seconds is h(t)=15t−4.9t^2 . Compute the average velocity of the stone over the given time intervals.

a) [1,1.05]

b) [1,1.01]

c) [1,1.005]

d) [1,1.001]

After solving the above question, Use the preceding exercise to guess the instantaneous velocity of the stone at t=1 sec
