Compute all parts of given problem:
Problem: Tiger Woods hits a golf ball off grass into a lake. The splash of the ball is 145 meters away from where it was hit. There is no change in y between where it was hit and the splash so the surface of this problem is 'level'. If the angle of inclination of the initial velocity of the ball with respect to the horizontal is 40 degrees:
Part A: What is the time of flight, the time from launch off the grass to landing in the lake?
Part B: What is the magnitude of the x-component of the initial velocity of the ball?
Part C: What is the magnitude of the initial velocity of the ball?
Please show work and steps and equations you used for above problem.
