We use the Work formula to solve for the unknown in the problem which is W = F x d. First, we solve for the Net Force acting on the car. The Net Force is the summation of all forces acting on the object. For this case, we assume that Friction Force is negligible thus the Net Force is equal to:
F = mgsinα in terms of SI units and in terms of english units we have F = m(g/g₀)(sin α) where g₀ is the proportionality factor, 32.174 ft lb-m / lb-f s²
F = 2500 (32.174/32.174) (sin 12°) = 519.78 lb
W = Fd = 519.78 lb (400 ft) = 207912 ft - lb or 20800 ft-lb
If it’s silver and greater than 1 it would be a quarter
Answer:
the answers are a and d
Step-by-step explanation:
x+x+x=3x and you can't add a constant (2) to a variable(3x) so it would just be 3x+2
A. 
is the secant line on the below circle.
<u>Step-by-step explanation:</u>
The intersection of the circle will result in either Tangent or Secant. Secant is a line intersecting a circle at two different point. This concept explains the relation between the circle and line intersecting it.
From the given diagram,
The 
and 
intersects the circle at the point H and I.
∴ It can also represented that the 
and intersects at a point G.
From the given options is the secant line that intersects the circle twice.
