Ok so I'm havin just a bit of trouble with this problem...(adsbygoogle = window.adsbygoogle || []).push({});

ok here it is.

A snowball rolls off a barn roof that slopes downward at an angle of 40 Degrees. 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.

A)How far from the edge of the barn does the snowball strike the ground if it doesn't srike anything else while falling?

B)A man 1.9 m tall is standing 4.0 m from the edge of the barn. Will he be hit by the snowball?

Part A: ok this was easy I got this:

tan (40 degrees) = X/15

X ≈ 11.75 m

(X = distance from the edge of the barn to where the snowball strikes the ground)

Part B: I'm stumped here I'm not even sure what approach to take...

I'm guessing I have to caculate the path of the snowball. And see if it hits him. (I'm not sure how to do this i'm guessing using (1/2at^2+Vit+Xi)

(i = initial)

Any help would be appreciated thanks. :)
