Why does a projectile maintain its horizontal component of velocity?
Because there's no horizontal force acting on it that would change its horizontal component of velocity. (In practice, that's not completely true, since the frictional 'force' of air resistance acts in any direction. But outside of air resistance, there's nothing else acting horizontally on the projectile.)
Why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?
Since the velocity is constant due to the fact that there are no external forces acting in the horizontal direction, if you neglect air resistance, therefore, the horizontal velocity of a projectile is constant.

The coefficients of friction between a block of mass 1 kg and a surface are s0.64 and k0.42 Assume the only other force acting on the block is that due to gravity what is the magnitude of the fr?
In order for the frictional force to come into play the block must be moving or on the verge of moving. The Frictional force opposes the motion of the block or its "impending" motion. If the block is just sitting on a table with no horizontal forces trying to get it moving then the frictional force is zero.
Is gravity acting on a moving bicycle?
Of course.
What is the resulting motion of forces acting on a unbalanced bicycle?
Constant acceleration is the resulting motion of forces acting on an unbalanced bicycle.

If a cart is observed moving at a constant velocity along a horizontal frictionless track is there a constant net force acting on it in the direction of motion?
No force is acting on it. Constant velocity means no acceleration, which means no force, from f=ma, no 'a' no force.

Of course.
If a box is sliding along at a constant speed and the force of friction on the box is 100n what is the net force on the box?
If the box is sliding along at a constant speed, the net force acting on the box is zero.If the net force was not zero, the box would either be speeding up or slowing down.Non-zero net forces acting on objects cause the objects to accelerate. Therefore, if the net forces is not zero, the velocity of the object could not be constant.
A horizontal force of 100 N pushes a box across a floor at a constant speed. what is the force of friction acting on the box?
If the horizontal velocity is constant, then the horizontal acceleration is zero,and the net horizontal force is zero.But if you are saying that the body was in constant motion and after that the force was applied, then the body will acccelerate because of the force. The net force applied on the body would be equal to the force applied to it when the body was in constant motion as here the force is in direction of the motion and hence the angle will be 0 giving the value of cos 0º as 1. Hence there would be no reduction in the net force
A horizantall force of 100N acting on a body of mass 40 kg speed of body is 20ms what willbe resultant force?
The speed of the object is given as "20 m/s", period, and there is no information given concerning the direction of its motion, or any change in the direction.. Since the speed of the object and its direction are constant and not changing, the net forces on it ... the resultant of all gravitational, frictional, and horizontal forces ... is zero.
What is horizontal acceleration?
It is acceleration in the horizontal direction. This would happen as a result of a net horizontal force acting on a body.
