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

A projectile is launched with an initial speed of 30 m/s atan angle of 60° above the horizontal. What are the (a) magni-tude and (b) angle of its velocity 2.0 s after launch, and (c) is theangle above or below the horizontal? What are the (d) magni-tude and (e) angle of its velocity 5.0 s after launch, and (f) is theangle above or below the horizontal?

After a projectile is fired into the air, what is the magnitude of the acceleration in the y-direction? (Assume no air resistance.)A.9.8 m/s2B.19.6 m/s2C.0 m/s2D.4.9 m/s2

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

A projectile is aimed at a mark on a horizontal plane through the point of projection and falls 6 m short when its elevation is 30∘ but overshoot the mark by 9 m when its elevation is 45∘. The angle of elevation of projectile to hit the target on the horizontal plane

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.
