Answer:
Horizontal acceleration=0
Step-by-step explanation:
Horizontal Launching
When an object is launched horizontally at a certain speed
, only one force will be acting throughout the whole duration of the motion: the force of gravity. If no effect of the wind is to be considered, then the horizontal speed will not change over time. It means the horizontal acceleration is zero. Please note the vertical acceleration is not zero, it is in fact, the acceleration of gravity (0.8 m/sec^2)
