Answer:
The average force exerted by the water on the ground is 17.53 N.
Explanation:
Given;
mass flow rate of the water, m' = 135 kg/min
height of fall of the water, h = 3.1 m
the time taken for the water to fall to the ground;
mass of the water;
the average force exerted by the water on the ground;
F = mg
F = 1.789 x 9.8
F = 17.53 N
Therefore, the average force exerted by the water on the ground is 17.53 N.
Answer:
a = 0.154 [m/s^2]
Explanation:
To solve this problem we must use the following formula of kinematics.
where:
Vf = final velocity = 0
Vi = initial velocity = 100 [km/h]
t = time = 3 [min] = 180 [s]
Now we need to convert the velocity from [km/h] to [m/s]
0 = 27.77 - (a*180)
a = 0.154 [m/s^2]
Note: the negative sign of the equation shows, that the car slows down until it stops
