Factor the formula and find the value of h for t = 2 seconds

Question

Bullet: A bullet is fired from a gun with a velocity of 100 m/s. The equation for the height of the bullet is h = -16t² + 32t + 128. Factor the formula and find the value of h for t = 2 seconds.



Answer 1

a. Factor

h = -16t² +32t +128

h = -16(t² - 16t -8)

h = -16(t-8)(t+2) full factor

b. Evaluate

h(2) = -16(2)² +32(2) + 28 Just simplify this
