1. The problem statement, all variables and given/known data A golfer strikes a stationary golf ball, and the force applied by the club on the ball varies as shown in the graph below. Use this graph to determine the final speed of the golf ball. The mass of the golf ball is 0.1kg 2. Relevant equations Area of triangle = 1/2bh (then times by two for the full area.) Or AvgFt=m(v-u) 3. The attempt at a solution I tried avgF*t= m(v-u) and put 100*0.04=0.1(v-0) = 4/0.1 = 40m/s also tried Area of Triangle = 1/2bh = 0.5*0.04*100 = 2 Then 2*2 = 4m/s to get the full triangle.
