well the net force would be zero because the forces have canceled to each other. The object will be at rest
So the forces from opposite side are the same amount of force that has been apllied thats why its ZERO and thats why it will be at REST because the first law states that AN OBJECT IN MOTION WILL STAY AT MOTION AND AN OBJECT AT REST WILL STAY AT REST UNLESS ACTED UPON BY AN UNBALANCED FORCE.
A rock is dropped into a well and you hear it hit the water 3.0 s later. Ignoring air resistance, how far down is the water?
Note: sound wave travels at a speed of approximately 343 m/s
Considering that you hear the sound after 3.0 seconds the moment the stone hit the water. This means the sound created by the stone in hitting the water takes 3.0 seconds to be heard by you. We can solve for distance using the formula distance = velocity × time.
v (velocity) = 343 m/s
t (time) = 3.0 seconds
d (distance) = ? unknown
distance = velocity × time
= 343 m/s × 3.0 s (cancel the unit second)
= 1,029 meters
the distance is 1,029 meters
Hope it helps=)
