Until a train is a safe distance from the station, it must travel at 5 m/s. Once the train is on open track, it can speed up
nignag [31]

Answer:

The acceleration of the train is 5 m/s².

Explanation:

Acceleration is the change in velocity over a given time interval.

Therefore, acceleration is given as:

a=\frac{v_{f}-v_{i}}{\Delta t}

Where, v_{i}\textrm{ and }v_{f} are initial and final velocities and \Delta t is the time interval.

Here, v_{i}=5\textrm{ m/s},v_{f}=45\textrm{ m/s},\Delta t=8\textrm{ s}

This gives,

a=\frac{45-5}{8}=\frac{40}{8}=5\textrm{ }m/s^{2}

Therefore, the acceleration of the train is 5 m/s².

Which graph showing constant acceleration correctly places the independent and dependent variables?
shtirl [24]

Answer:

graph 1

Explanation:

acceleration is defined as change in velocity/ change in time.

A constant acceleration should have a linear line.

Since velocity is in the numerator of the formula it is the dependent variable which will go on the y axis. thus making time the independent going on the x axis.

This makes sense because velocity should depend on time not the other way around. This therefore making the right answer graph 1

Dawn and Timothy are sailboating in Lake Obewon. Starting from rest near the shore, they accelerate with a uniform acceleration
castortr0y [4]

Answer:

The value is s =63.18 \  m  

Explanation:

From the question we are told that

   The uniform  acceleration is   a =  0.39 \ m/s^2

   The time considered is t =  18 \  seconds

Generally the from kinematic equation we have that

          s =  ut + \frac{1}{2} at^2

Given that the boat started from rest , the initial velocity is  u =  0  m/s  

So

       s =  0 * 18 + \frac{1}{2} *0.39 * 18^2

=>      s =63.18 \  m
