Question

At the top of the trajectory of a projectile, thrown at an angle of projection $\theta <90{}^{\circ },$ its:

• A. velocity is zero
• B. velocity is parallel to the direction of acceleration
• C. velocity is anti-parallel to the direction of acceleration
• D. acceleration is zero
• E. velocity is perpendicular to the direction of acceleration

Answer 1

Answer: (E)

At the highest point (P) of the project trajectory, vertical component of velocity is zero, only horizontal component exists which is perpendicular to the direction of acceleration.
