If air resistance is neglected what is the motion of an object projected at an angle consists of a uniform downward acceleration combined with what?
a constant horizontal speed
What is the acceleration of falling bodies?
Near Earth's surface, the acceleration is about 9.8 meters/second2, assuming air resistance can be neglected.
If air resistance can be neglected how does the acceleration of a ball that has been tossed straight upward compare with its acceleration if simply dropped?
The acceleration is the same, which is the acceleration due to gravity. About 10m/s^2
Is it possible for a body moving with a uniform speed to have acceleration?
Yes. This is exactly the case when an object is thrown on the surface of the Earth. Consider an (American) football thrown in the air. This ball has the force of gravity accelerating it downward, but there is no force acting on it horizontally, thus there is no acceleration horizontally. As a result, since acceleration is the rate of change in velocity, the velocity in the vertical direction is changing, whereas the velocity in the horizontal direction is not.
Can the masses be neglected if the masses are equal?
Yes. If the masses are the same, then it can be considered as a constant and thus neglected.

What is the horizontal acceleration of a projectile?
The horizontal acceleration i.e. Vx throughout the trajectory remains constant only of the air resistance is neglected. The gravity can affect the y-component of velocity but is unable to affect its x-component. Acceleration (delta V) does not occur unless a change comes into play per Newton. Gravity does not effect x but air resistance would. Likewise, projectiles launched from e.g. an explosion experience a reducing delta V in that acceleration from an explosion is subject to the inverse square rule.
