A runner starts from rest and in 2 s reaches a speed of 7 m/s. If we assume that the speed changed at a constant rate (constant
PtichkaEL [24]

Answer:

v=3.5\frac{m}{s}

Explanation:

The average speed is defined as:

v=\frac{\Delta x}{\Delta t}

Using the equations for uniformly accelerated motion, we calculate the runner's acceleration:

a=\frac{v_f-v_o}{2}\\a=\frac{7\frac{m}{s}-0\frac{m}{s}}{2s}\\a=3.5\frac{m}{s^2}

Now, we can calculate the distance that the runner travels:

\Delta x=v_0t+\frac{at^2}{2}\\\Delta x=(0\frac{m}{s})(2s)+\frac{3.5\frac{m}{s}(2s)^2}{2}\\\Delta x=7m

Finally, we calculate the runner's average speed:

v=\frac{7m}{2s}\\v=3.5\frac{m}{s}

Answer:

p(a) * p(b) = .01923

p(b) = .01923 / .07692 = .2500
