rosijanka [135]

Answer:

A) \frac{g}{b}(1-e^{-bt})

Explanation:

Since a = g - bv,

We can substitute a = dv/dt into the equation.

Then, the equation will be like dv/dt = g - bv.

So we got first order differential equation.

As known, v = 0 at t = 0, and v = g/b at t = ∞.

Since \frac{dv}{dt}= g - bv = b( \frac{g}{b} - v) ⇒ \frac{dv}{ \frac{g}{b} - v}= bdt

So take the integral of both side.

- ln (\frac{g}{b} - v) = bt + C

Since for t=0, v = 0 ⇒ C =- ln (\frac{g}{b})

v = \frac{g}{b} + e^{-bt-ln(\frac{g}{b})} = \frac{g}{b}- \frac{g}{b}e^{-bt} = \frac{g}{b}(1-e^{-bt})

A motorcyclist travels with an average speed of 6 m/s . If the cyclist is going to a friend's house 36 m away , how much time wi
vodka [1.7K]

Answer:

<h2>6 s</h2>

Explanation:

The time taken by the cyclist can be found by using the formula

t  = \frac{d}{v}  \\

v is the velocity

d is the distance

From the question we have

t =  \frac{36}{6}  \\  = 6

We have the final answer as

<h3>6 s</h3>

Hope this helps you
