Answer:
the answer is 49ft/s
Explanation:
if you look for the equations of uniformly accelerated motion you find the following
Vo=Vf-AT
Where
Vo=initial speed
Vf=final speed
A=aceleration
T=time
you replace and it's all
Vo=55-2x3
Vo=49ft/s
The similarity between a car at rest and a car moving at constant velocity is that the both cars have zero acceleration. the car at rest is not moving so its acceleration should also be zero. for the car at constant velocity, since the velocity of the car is not changing, and acceleration is change in velocity per time, that it why it is also zero
. Karst topography is a landscape formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves.
