Homework Help: Projectile Motion

  1. Oct 29, 2005 #1
    Problem: Harry accidentally falls out of a helicopter that is traveling horizontally at 70 m/s. He plunges into the water below 3 seconds later. Assuming no air resistance, what is the horizontal distance he travels while falling?

    why would you use the formula d= s*t ?

    Please help i really don't understand!

    You are given a horizontal velocity, and a time. You need to find the distance traveled.

    Have you thought about this for any length of time?
