Question

In case of a projectile motion, what is the angle between the velocity and acceleration at the highest point?

• A. $0^o$
• B. $45^o$
• C. $90^o$
• D. $180^o$

Answer 1

Answer: (C)

At the highest point, velocity is acting horizontally and acceleration (= acceleration due to gravity) is acting vertically downwards. Therefore, at the highest point the angle between velocity and acceleration is $90^o$.
