Question
**Educational Website Content:** ### Projectile Motion on Planet Exidor A physics student on Planet Exidor throws a ball, which follows a parabolic trajectory as shown in the figure. The positions of the ball are recorded at 1-second intervals, from \( t = 0 \, \text{s} \) to \( t = 3 \, \text{s} \). At \( t = 1 \, \text{s} \), the ball's velocity is given by \(\vec{v} = (2.0\hat{\imath} + 2.0\hat{\jmath}) \, \text{m/s}\). #### Diagram Explanation: The diagram illustrates the trajectory of the ball. The x-axis represents time in seconds, while the y-axis represents the height or vertical distance. Key points on the curve indicate the ball’s position at 0, 1, 2, and 3 seconds. The vector \(\vec{v}\) at \( t = 1 \, \text{s} \) shows the velocity direction and magnitude at that point. ### Exercises: #### Part A: **Question:** Determine the ball's velocity at \( t = 0 \, \text{s} \). **Choices:** - \( 2.0\hat{\imath} \, \text{m/s} \) - \( (2.0\hat{\imath} + 4.0\hat{\jmath}) \, \text{m/s} \) - \( (2.0\hat{\imath} + 2.0\hat{\jmath}) \, \text{m/s} \) - \( (2.0\hat{\imath} - 2.0\hat{\jmath}) \, \text{m/s} \) Click "Submit" once you have made your selection. #### Part B: **Question:** Determine the ball's velocity at \( t = 2 \, \text{s} \). **Choices:** - \( 2.0\hat{\imath} \, \text{m/s} \) - \( (2.0\hat{\imath} + 4.0\hat{\jmath}) \, \text{m/s} \) - \( (2.0\hat{\imath} + 2.
