Can anyone tell me if my answers are right or wrong? thanks(adsbygoogle = window.adsbygoogle || []).push({});

A boy with a slingshot wants to hit a can on top of a pole. The can is a distance of 15 meters from the boy at an elevation of 30 degrees above the horizontal. The boy aims the slingshot directly at the can and projects a stone with a speed of 22 meter/second. It misses the can. (We want to find out bad the aim was.)

a) Find the x- and y- components of the displacement of the can from the child.

12.99 x + 7.50 y

b) What is the initial velocity of the stone?

19.05 x + 11.0 y

c) When does the stone pass directly below the can?

0.682 seconds

d) Find the height differential between the can and the path of the stone.

2.28 meters

e) Find the range of the stone (i.e. where it lands).

14.0 meters
