An arrow is shot vertically upward from a platform 8ft high at a rate of 157ft/sec. When will the arrow hit the ground? Use the formula: h=−16t2+v0t+h0 . (Round your answer to the nearest tenth.)

Answer 1

Answer 2

When the arrow hits the ground, h = 0.

So, -16t² + 157t + 8 = 0

Use the quadratic formula to solve for t.
