🤓 Based on our data, we think this question is relevant for Professor Sheets' class at RIT.

# Solution: A snowball rolls off a barn roof that slopes downward at an angle of 40°. The edge of the roof is 14.0 m above the ground, and the snowball has a speed of 7.00 m/s { m m/s}as it rolls off the roof. Ignore air resistance. Assume the coordinate origin is at the point on the roof where the snowball rolls off and that the positive x direction is to the right and the positive y direction is upwards.(a) How far from the edge of the barn does the snowball strike the ground if it doesn't strike anything else while falling?(b) Draw y-t graphs for the motion in part A.(c) Draw x-t graphs for the motion in part A.(d) Draw vx-t graphs for the motion in part A.(e) Draw vy-t graphs for the motion in part A.(f) A man 1.9 m tall is standing 4.0 m from the edge of the barn. Will he be hit by the snowball?

###### Problem
A snowball rolls off a barn roof that slopes downward at an angle of 40°. The edge of the roof is 14.0 m above the ground, and the snowball has a speed of 7.00 m/s as it rolls off the roof. Ignore air resistance. Assume the coordinate origin is at the point on the roof where the snowball rolls off and that the positive x direction is to the right and the positive y direction is upwards.
(a) How far from the edge of the barn does the snowball strike the ground if it doesn't strike anything else while falling?
(b) Draw y-t graphs for the motion in part A.
(c) Draw x-t graphs for the motion in part A.
(d) Draw vx-t graphs for the motion in part A.
(e) Draw vy-t graphs for the motion in part A.
(f) A man 1.9 m tall is standing 4.0 m from the edge of the barn. Will he be hit by the snowball?
