At what point of a projectile motion acceleration and velocity are perpendicular to each other?Only one correct answerA.

For general projectile motion, when the projectile is at the highest point of its trajectoryGroup of answer choicesits acceleration is zero.none of theseits velocity is perpendicular to the acceleration.the horizontal component of its velocity is zero.its velocity and acceleration are both zero.the horizontal and vertical components of its velocity are zero.

When a projectile is fired at an angle, what is the acceleration in the horizontal direction?Select one:a.Depends on the angle of projectionb.Equal to the initial velocityc.9.8 m/s²d.0 m/s²

Which of the following statements is true for the acceleration of the projectile (of the previous question)?Group of answer choicesIt is zero in horizontal and g downward in vertical directionIt is g downward in both horizontal and vertical directionsIt is g downward in horizontal direction and zero in vertical directionIt is zero in horizontal and g upward in vertical directionIt is zero in both horizontal and vertical directions

Which of the following statements is true for any location of the projectile in its trajectory?Group of answer choicesTime to travel the horizontal distance and time to travel the vertical distance are the sameTime to travel horizontal distance is zero but time to travel the vertical distance is 9.8 secondsTime to travel the horizontal distance is 9.8 seconds but the time to travel the vertical distance is zeroMore information is needed to answer this questionCorrect answer to this question will depend o
