SOLUTION: This projectile function: h(t)=-16t^2+vt+k applies to any object projected upward with an initial velocity v, from a height k but not to objects under propulsion (such as a rocket)
Question 1128212: This projectile function: h(t)=-16t^2+vt+k applies to any object projected upward with an initial velocity v, from a height k but not to objects under propulsion (such as a rocket). Consider this situation and answer the following questions.
Height of a projectile: A projectile is thrown upward with an initial velocity of 176 ft/sec. After t seconds, its height h(t) above ground is given by the function h(t)= -16t^2+176t.
a) find the projectile's height above the ground after 2 sec.
a) Sketch the graph modeling the projectile's height.
c) What is the projectile's max height? What is the value of t at this height?
d) how many seconds after it is thrown will the projectile strike the ground? Answer by ikleyn(52781) (Show Source):
