In a softball game, a .200 kg softball crossed the plate at 15 m/s at an angle of 30 degrees below the horizontal. The batter hits the ball toward the center field, giving it a velocity of 45 m/s at 60 degrees above the horizontal
a) Determine the impulse delivered to the ball
_______i + _______j (Assume x axis is positive toward the center field and the y axis to be positive upward)
b) If the force increases linearly for 4 ms, holds constant for 20.0 ms, then decreases to 0 linearly for another 4.00 ms, what is the maximum force on the ball?
_________ magnitude
_________ (degrees above the horizontal)
please also describe the geometry of the vectors !!!
