Answer:

He calculated his average speed.

Explanation:

Waldo calculated an average of his speed in 2 hours rather than his speed whilst driving which means instead of doing 50/1 hour = 50 mph, he did 50/2hours which is how he got 25 mph. Hope this helps!

Answer:

a) t =12[s]; b) x = 348[m]

Explanation:

We can solve this problem using the following kinematics equations:

$v_{f}= v_{o}+a*t$

where:

vf = final velocity = 12 [m/s]

vo= initial velocity = 6 [m/s]

a = acceleration = 0.5[m/s^2]

t = time [s]

Now clearing the time t, we have:

$t=\frac{v_{f} -v_{o} }{a} \\t = \frac{12-6}{0.5} \\t=12[s]$

We can calculate the displacement for the first 12 [s] then using the equation for the constant velocity we can calculate the other displacement for the 20[s].

$v_{f}^{2}= v_{o}^{2}+2*a*x_{1} \\therefore\\x_{1} =\frac{v_{f}^{2}-v_{o}^{2}}{2*a} \\x_{1} =\frac{12^{2}-6^{2}}{2*.5}\\x_{1} =108[m]$
