Question
A projectile is fired at an angle θ and reaches
maximum height H and range R. The angle between velocity and acceleration at the highest point is:Solution
At the highest point of a projectile’s motion: ● Velocity is horizontal, since the vertical component becomes zero. ● Acceleration is always vertically downward, due to gravity. Therefore, at the highest point, velocity is horizontal and acceleration is vertical, making them perpendicular.
