6) A snowball rolls off a barn roof that slopes downward at angle of 40 degrees below the horizontal. The edge of the roof is 14m above the ground, and the snowball has a speed of 7 m/s as it rolls off the roof. (A) How far from the edge of the barn does the snowball strike the ground? (B) A man 1.9 m tall is standing 4 meters from the edge of the barn. Will he be hit by the snowball? 7) If gravity on the moon is 1/6 of gravity here on earth compare the height of a rocket that launches straight up with an initial speed of 30m/s here on earth to what it would be on the moon. 8) A balloon is descending with a constant downward velocity of 13.2 m/s A stone is thrown horizontally from the balloon with an initial velocity of 17.3 m/s to the path of the descending balloon. The person in the basket sees the stone hit the ground 5.80 s after being thrown. Assume that the balloon continues its downward descent with the same constant speed of 13.2 m/s. a) How high was the balloon when the rock was thrown out? b) How high is the balloon when the rock hits the ground? c) At the instant the rock hits the ground, how far is it from the basket? d) Just before the rock hits the ground, find its horizontal and vertical velocity components as measured by an observer at rest in the basket. e) Just before the rock hits the ground, find its horizontal and vertical velocity components as measured by an observer at rest on the ground
