A pitcher throws a fastball horizontally towaRd home plate 18.39 meters away . If the ball is traveling at a speed of 40.0m/s neglecting air friction ,how long does it take for the ball to get to home plate

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
