2 3. A bicycle has a constant acceleration from an initial speed of 15.0 m/s in the forward direction to a final speed of 3.00 m/s in the forward direction. If the bicycle moves forward a distance of 72.0 m, what are the acceleration, d, and the time interval, At, for this trip? 4. A soccer ball is kicked with an initial speed of 30.0 m/s from the level ground at an initial angle of 40.0 above the horizontal direction. If one may take for the gravitational acceleration, g = 9.80 m/s? downward, and neglecting any effects due to air resistance, a. what is the maximum height, y, reached by the ball, and b. what are the speed, | v|, of the ball at its maximum height and how long, At, does it take for the ball to reach this maximum height
