Surfing For In A Slow-pitch Softball Game A 0.200 Kg?

Donna asks…Physics Homework? I keep getting the wrong answer. Find impulse?In a slow-pitch softball game, a 0.200 kg softball crossed the plate at 10.0 m/s at an angle of 45.0° below the horizontal. The batter hits the ball toward center field, giving it a velocity of 48.0 m/s at 30.0° above the horizontal.
(a) Determine the impulse delivered to the ball.
N·s (magnitude)
° (above the horizontal)

(b) If the force on the ball increases linearly for 4.00 ms, holds constant for 20.0 ms,
