Explanation / Answer

False: acceleration at H is zero. Acceleration at H is g, acceleration due to gravity.

True: acceleration at B in X direction is zero. No force is acting in X direction.

False: The acceleration in Y direction at B is zero. The acceleration is g, acceleration due to gravity.

False: The velocity at A equal to velocity at H. Speed are equal because both are at same height, but not the velocities.

Greater than: speed at B is greater than speed at H.

Equal: Speed at H equal to speed at A.
