The object that is moving at a constant speed will slow down. Its new velocity will be determined by the original constant speed along with the new combined mass of the moving object and the additional "large mass."
It slows to a rest and then starts moving in the opposite direction at constant acceleration in that direction.
Force increases.
The coin will land straight back down in the same spot from where it was dropped in the bus, assuming the bus is moving at a constant speed in a straight line without any sudden changes in acceleration. This is because the coin is moving with the bus at the same velocity when dropped.

F=ma. F=0, a=0. The object is either moving a constant velocity or not moving at all.
The word is "stationary" for not moving, and "constant velocity" for moving at a constant speed in the same direction.
The graph of displacement vs. time for something moving at a constant positive velocity would be a straight line sloping upwards, indicating a linear increase in displacement over time.
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
Since the truck is moving at constant velocity, the rock will also fall straight down due to gravity from the perspective of an observer inside the truck. The horizontal motion of the truck does not affect the vertical motion of the falling rock. Therefore, the rock will follow a vertical straight-line path and hit the floor directly below where it was dropped.
the pressure remains the same
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
