Question
Francisco kicks a soccer ball with speed 35.8 m/s at an angle of 30.0 degrees above
the horizontal. While the ball is in the air, which of these statements is/are true?
Ignore air resistance. [select all that apply]
The trajectory (in x and y) is triangular in shape
The trajectory (in x and y) is parabolic in shape
The acceleration of the ball is -g y
The acceleration of the ball is -g sin (0) ŷ
| The only force acting on the ball is the force of gravity.
| The total time the ball is in the air is equal to twice the time it takes to reach its
maximum height.
| The maximum height that the ball reaches is equal to half of the total distance
the ball travels horizontally
Displacement in the horizontal direction is a quadratic function of time.
