A car travels 300 km east and then 300 km south. Finally, it comes back to the starting point by the south-east route. Throughout the journey the speed is constant at 72 km/hr. The average velocity for the whole journey if time taken is 4.3 hours is *
Answers
Explanation:
There is more to motion than distance and displacement. Questions such as, “How long does a foot race take?” and “What was the runner’s speed?” cannot be answered without an understanding of other concepts. In this section we will look at time, speed, and velocity to expand our understanding of motion.
A description of how fast or slow an object moves is its speed. Speed is the rate at which an object changes its location. Like distance, speed is a scalar because it has a magnitude but not a direction. Because speed is a rate, it depends on the time interval of motion. You can calculate the elapsed time or the change in time, Δt , of motion as the difference between the ending time and the beginning time
Answer:
here is your answer
Explanation:
please mark as brain list
please correct the last step
therefore the velocity = 0/4.3
= 0km/h
