Question

4 pt q13: find the total speed in m/s. show your work. include all units. a plane flies 180 km east in 30 minutes. 5 pt q14: find the total velocity in m/s. show your work. include all units.

Explanation:

Step1: Convert distance to meters

$180\ km = 180\times1000\ m=180000\ m$

Step2: Convert time to seconds

$30\ minutes = 30\times60\ s = 1800\ s$

Step3: Calculate speed

Speed $v=\frac{d}{t}$, where $d$ is distance and $t$ is time. So $v=\frac{180000\ m}{1800\ s}=100\ m/s$

For velocity, since the plane moves in a straight - line (east - direction) and speed and velocity magnitudes are the same in a straight - line motion without changing direction, the velocity is also $100\ m/s$ east.

Answer:

Q13: $100\ m/s$
Q14: $100\ m/s$ east
