Answer:
Since the five forces applied are all in the same direction with the motion of the sled, to solve for the net force, add the five forces together. Therefore, the net force is 30 Newtons.

Answer:
18.62 m/s
Explanation:
Given that:
A liquid with a density of 900 kg/m 3 is stored in a pressurized, closed storage tank. 
Diameter of the tank = 10 m 
The absolute pressure in the tank above the liquid is 200 kPa = 200, 000 Pa
At pressure of 200 kPa   ; the final velocity = 0 
Atmospheric pressure at 5cm = 101325 Pa
We are to calculate the initial velocity of a fluid jet when a 5cm diameter orifice is opened at point A?
By using Bernoulli's theorem between the shaded portion in the diagram;
we have:




where;
Pa = atmospheric pressure = 101325 Pa
 = density of liquid = 900 kg/m³
 = density of liquid = 900 kg/m³
 = initial velocity = ???
 = initial velocity = ???
g = 9.8 m/s²
 = height of the hole from the buttom
 = height of the hole from the buttom
 = height of the liquid surface from the button
 = height of the liquid surface from the button


Thus, the initial  velocity of the fluid jet  = 18.62 m/s
 
        
             
        
        
        
Answer:
momentum = mass • velocity
v= 17.5/2.5
= 7 m/s
