Question

A projectile is projected with speed $u$ at an angle ${30}^o$ from the ground. The angle between acceleration of projectile and its velocity at time of striking the horizontal ground is

• A. ${30}^o$
• B. ${60}^o$
• C. ${45}^o$
• D. $0^o$

Answer 1

The correct option is B ${60}^o$

as from the above diagram we can see that the angle of object in projectile motion is same at the starting and striking time

so we can see that g and velocity

have an angle of 60º between them

so option B is correct answer
