A street light is at the top of a 13.0 ft. tall pole. A man 6.3 ft tall walks away from the pole with a speed of 3.5 feet/sec al
amm1812

Answer:

\dfrac{dL}{dt}=5.82 \ ft/s

Explanation:

given,

street light height = 13 ft

man height = 6.3 ft

speed of the man = 3.5 ft/sec

\dfrac{H}{L} = \dfrac{h}{l}

\dfrac{H}{L} = \dfrac{h}{L-x}

\dfrac{L}{H} = \dfrac{L-x}{h}

hL = H(L-x)

hL = HL-Hx

L = \dfrac{Hx}{H-h}

L = \dfrac{13x}{13-6.3}

L = 1.94 x

\dfrac{dL}{dt}=\dfrac{dL}{dx}\dfrac{dx}{dt}

\dfrac{dL}{dt}=1.94\times 3

\dfrac{dL}{dt}=5.82 \ ft/s

Sprinting near the end of a race, a runner with a mass 63 kg accelerates from a speed of 25 m/s to a speed of 26 m/s in 54 s. To
gavmur [86]

Answer:

1.1655 N

Explanation:

Given that,

Initial speed, u = 25 m/s

Final speed, v = 26 m/s

Time taken, t = 54 s

So, Applying equation of motion as:

v=u+at\\\Rightarrow a=\frac{v-u}{t}\\\Rightarrow a=\frac{26-25}{54}\ m/s^2\\\Rightarrow a=0.0185\ m/s^2

According to the Newton's second law of motion:-

Force=Mass\times Acceleration

Mass = 63 kg

So,

Force=63\times 0.0185\ kgm/s^2

<u>Force = 1.1655 N</u>
