A stone is kicked so that it leaves the ground with an initialvelocity of 10 m/s at an angle of 37 degrees. The stone is kickedtoward a loading dock 3 meters away which is 1 meter inheight.
a.) what are the components of the stone's initial velocity?
b.) how high is it when it goes over the edge of the dock?
c.) what is the maximum height it reaches?
d.) how far past the edge of the dock has it gone when it reaches maximum height?
