continues to spread globally, with supply chain disruptions resulting in declines in income and employment. There are, hence, additional worries that the disease could threaten food chains and supply systems and stoke inflation. Water tariffs are also at risk if utilities are not supported financially to contain production costs and keep revenue streams. The Economist magazine recently invoked that notion by stating that shutters businesses and leaves supermarket shelves bare, economists fret that the pandemic could lead to inflation making an unwelcome return.” Thus, we should take a look at how inflation and water tariffs have evolved in years to be able to foresee
The free body diagram consists of:
1) Weight force, which is a vertical arrow downward
2) A Normal force that is perpendicular to the ramp.
The Normal force can be decomposed in a vertical component and an horizontal component.
The vertical component, Ny, must equal the weight force, due to equilibrium (rest) condiition =>
Ny = weight = m*g = 5.5kg*9.8m/s^2 = 53.9 N
By geometry the vertical component of the Normal force, Ny is such that
cos (angle) = N / Ny => N = Ny * cos(angle)
=> N = 53.9N * cos(angle)
Now use that equation for each option:
a) 0 ° => N = 53.9N * cos(0) = 53.9N
b) 12° => N = 53.9 * cos(12) = 52.7N
c) 25° => N = 53.9 * cos(25) = 48.9N
d) 45° => N = 53.9 * cos(45) = 38.1N
