1.) For the two vector x1= (20 m) x^ and x2= (15 m) x^, compute and show graphically (a) x1 + x2, (b) x1 - x2, and (c) x2 - x1. [The one and the two after the x's are supposed to be subscripts.]

2.) Given two vectors A, which has a length of 10.0 and makes an angle of 45° below the -x-axis, and B, which has an x-component of +2.0 and y-component of +4.0, (a) sketch the vectors on x-y axes, with all their "tails" starting at the origin, and (b) calculate A + B.

3.) A 2.05 m tall basketball player takes a shot 6.02 meters from the basket (At 3-point line). If the launch is 25° and the ball is launches at the level of the players head, what must the release speed of the ball for the player to make the shot? The basket is 3.05 m above the floor.
