Question

The angle between the velocity and the acceleration at the highest point of a particle projected upwards at an angle of 30° with the horizontal is

• A. $0^{\circ }$
• B. $45^{\circ }$
• C. $90^{\circ }$
• D. $180^{\circ }$

Answer 1

Answer: (C)

The situation is shown in figure

At the highest point of its trajectory, the velocity and the acceleration are perpendicular, so the angle between them is $90^{\circ }$
