Question

The velocity of water flowing over a water fall is 12 m/sec. After going over the fall the water slows to 6 m/secin 3 seconds.
What is the acceleration of water?
Select one:
O a. 5 m/s2
O b. 2 m/s2
O C.-5 m/s2
O d.-2 m/s2​

Answer 1

Answer:

It is a retardation. Because the speed of water has decreased.

So, acceleration => Final velocity - Initial velocity / Time

=> acceleration = 6 - 12 / 3

=> acceleration = -2 m/s ^2

So, the answer is -2 m/s^2.
