The height,
h
, in meters of a projectile after
t
seconds can be represented by
h(t)=-4.9t^(2)+115t+12.5
a. What is the object's average rate of change over the interval
0,10
?
(h(10)-h(\theta ))/(10)=(-4.9(10)^(2)+115(10)+12.5+(-4.9(\phi )^(2)+115(\phi )+12.5))/(10)
=(660)/(10)=66
(b) What is the object's instantaneous velocity
a+t=10
? (c) What is the equation of the tangent line to
h(t)
at
t=10
(D) What is the object's accelerotion at
E=10
? (e) when is the object's instantaneous velocity equal to 0 ?
