Answer:

correct option is B. only applies to left-turning traffic

Explanation:

solution

according to traffic rule regulation , when we see signal with left pointing arrow it mean that we can move on the left side turn

and if we see left pointing signal with red arrow it meaning same as NO TURN ON RED

and when we see yellow arrow it also means the same as the yellow light

and if there is green arrow it mean we can freely now move on left

so here correct option is B. only applies to left-turning traffic

Assume you are an observer standing at a point along a three-lane roadway. All vehicles in lane 1 are traveling at 30 mi/h, all
garik1379 [7]

Answer:

Explanation:

Given data;

  • In line 1, v1 = 30mi/hr
  • in line 2, v2 = 45mi/hr
  • in line 3, v3 = 60mi/hr
  • therefore time mean speed = v1 + v2 + v3 /n
  • = VT = 45mi/hr

  • space mean speed ; Vs
  • harmonic mean = 1/V = 1/v1 + 1/v2 + 1/v3
  • V = 13.85mi/hr
  • Hence Vs = V x n = 3 x 13.85 = 41.55mi/hr

The velocity of a particle which moves along the s-axis is given by v = 2-4t+5t^(3/2), where t is in seconds and v is in meters
Brut [27]

Answer:

a) s = 42 m

b) V = 26 m/s

c) a = 11 m/s²

Explanation:

The velocity(V) = 2 - 4t + 5t^3/2 where t is in seconds and V is in m/s

a) To get the position, we have to integrate the velocity with respect to time.

We get the position(s) from the equation:

V=\frac{ds}{dt}

ds=Vdt

Integrating both sides,

s=\int\ {V} \, dt

s=\int\ {(2-4t+5t^{\frac{3}{2} })  \, dt

Integrating, we get

s=(2t-2t^{2} +2t^{\frac{5}{2} }+c)m

But at t=0, s(0) = 2 m

Therefore,

s(0)=2(0)-2(0)^{2} +2(0)^{\frac{5}{2} }+c  

2=0+0+0+c

c = 2

Therefore

s=(2t-2t^{2} +\frac{10}{5}t^{\frac{5}{2} }+2)m

When t = 4,

s=2(4)-2(4)^{2} +2(4)^{\frac{5}{2} }+2

s=8-32+64+2

s = 42 m

At t= 4s, the position s = 42m

b) The velocity equation is given by:

V=(2-4t+5t^{\frac{3}{2} })m/s

At t = 4,

V=2-4(4)+5(4)^{\frac{3}{2} }

V = 2 - 16 + 40 = 26 m/s

The velocity(V)at t = 4 s is 26 m/s

c) The acceleration(a) is given by:

a=\frac{dv}{dt}

a=\frac{d}{dt}(2-4t+5t^{ \frac{3}{2}})

Differentiating with respect to t,

a=-4+\frac{15}{2}t^{\frac{1}{2} }

a=(-4+\frac{15}{2}t^{\frac{1}{2} })m/s^{2}

At t = 4 s,

a=-4+\frac{15}{2}(4)^{\frac{1}{2} }

a=-4+15

a = 11 m/s²
