Hey!
---------------------------------------------------
Formula: Distance / Time = Speed
---------------------------------------------------
Solution:
Speed = 15/20 = 0.75cm/sec
Velocity = 5/20 = 0.25cm/sec
10 + 5 = 15 (distance traveled)
---------------------------------------------------
Answer:
Speed = 0.75cm/sec
Velocity = 0.25cm/sec going forward.
---------------------------------------------------
Hope This Helped! Good Luck!
Answer:
Average speed = 0.0075 m/s
Average velocity = 0.0025 m/s along forward direction
Explanation:
Speed is the ratio of distance and time and velocity is the ratio of displacement and time.
Distance traveled = 10 + 5 = 15 cm = 0.15 m
Displacement = 10 - 5 = 5 cm = 0.05 m
Time = 20 seconds
[tex]\texttt{Average speed = }\frac{\texttt{Distance}}{\texttt{Time}}\\\\\texttt{Average speed = }\frac{0.15}{20}=7.5\times 10^{-3}m/s\\\\\texttt{Average velocity = }\frac{\texttt{Displacement}}{\texttt{Time}}\\\\\texttt{Average velocity = }\frac{0.05}{20}=2.5\times 10^{-3}m/s[/tex]
Average speed = 0.0075 m/s
Average velocity = 0.0025 m/s along forward direction
