Assignment:
A boy kicks a ball horizontally near the edge of a boardwalk, with an initial speed of 9.0 m/s. A blowing wind gives the ball a constant horizontal acceleration of 12 m/s^2.
The ball falls into the water directly under the boy. Ignore the effect of air resistance on the vertical motion of the ball.
a. Determine the height of the boardwalk above water.
b. If the blowing wind reverses direction while maintaining the same strength, where does the ball fall when it is kicked with the same initial speed?
Provide complete and step by step solution for the question, use formulas.
