Question

In case of a projectile motion, what is the angle between the velocity and acceleration at the highest point ? (A) 0° (B) 45° (C) 90° (D) 180°

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°.

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

$0^{°}$

$4 5^{°}$

$9 0^{°}$

$18 0^{°}$

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 $9 0^{°}$ .
