After the snowstorm , a boy and a girl decides to have a snowball fight. The girl uses a large slingshot to shoot to shoot snowballs travel with an initial velocity of V0 .1) In terms of the initial velocity, V0 , and the launch angle , theta, for what amount of time, delta t , will a snowball travel before it reaches its maximum height above the ground ? (Hint: Recall that Vf = 0 when an object reaches its maximum height.)
2) What is the maximum height , h, above the ground that a snowball reaches after it has launched ?
3) What is the horizontal distance , x , the snowball has traveled when it reaches its maximum height ?

Given the following scenario , calculate the x and y components of each golf shot.One of the holes on a golf course lies due east to the tee . A novice golfer flubs his tee shot so that the ball lands only 64 m directly northeast of the tee . He then slices the ball 30 degrees south of east so that the ball lands in a sand trap 127 m away. Frustrated , the golfer then blasts the ball out of the sand trap , and the ball lands at a point 73 m away at an angle 27 degrees north of east . At this point , the ball is on the putting green and 14.89 m due north of the hole . To his amazement , the golfer then sinks the ball with a single shot .
1) Use the algebraic formulas to find the x and y components of eah displacement vector .Shot 1-x component --------------- y component ---------------------
Shot 2-x component --------------- y component ---------------------
Shot 3-x component --------------- y component ---------------------
