To find out the cyclist's average speed you simply have to divide 50.0km by 2.5 to find the answer. Therefore the cyclist's average speed is 20.0 km an hour.

Answer is 20.0 km per hour.


<em>Explanation;</em>


S = d/t


Where, S is the speed, d is the distance and t is the time taken.


Here,

    d = 50.0 km

     t = 2.5 hours


By applying the formula,

  S = 50.0 km / 2.5 hours

      = 20.0 km per hour


Hence, the average speed of the cyclist is 20.0 km per hour.

elena55 [62]

4)

the arrow touches the ground when the heigth is 0

so we need to replace h=0 and solve for t

\begin{gathered} h=17t-5t^2 \\ 0=17t-5t^2 \\ 0=t(17-5t) \\ 0=17-5t \\ 5t=17 \\ t=\frac{17}{5}=3.4 \end{gathered}

<em>the arrow tuches the ground at 3.4 seconds</em>

5)

F=m\times a

replacing

185=m\times13.7

<em>solve for m</em>

\begin{gathered} m=\frac{185}{13.7} \\  \\ m=13.50 \end{gathered}

<em>the mass is 13.50Kg</em>
