<u>Analysing the Question:</u>
We know that equilibrium is the state of a body when it has equal and opposite forces being applied on it
In this case, a net downward force of 496N is being applied and a net upward force of (106 + 106 + 142 + x) N
<u>Finding the missing force:</u>
Since we have to achieve equilibrium, the net upward forces have to be equal to the net downward forces
So, (106 + 106 + 142 + x) = 496
354 + x = 496
x = 496 - 354
x = 142 N
Therefore, the missing force is 142 N
Answer:
1.68N
Explanation:
W=F*d
KE=1/2*M*V^2
M=32kg
V= 5.1m/s
D=50m
0.5(32)(5.1^2)= 416 J
Initial energy=500 J
final energy= 416 J
lost energy= 500-416
heat lost to friction=84 J
84=F*50
84/50=F*50/50
F=1.68N
