Question

A car travels along a straight road to the east for 120
meters in 5 seconds, then go the west for 60 meters in 1 second Determine
average speed and average velocity​

Answer 1

Answer:

Average speed 30m/s

Average velocity 15m/s

Answer 2

To east=120 m in 5 sec

so speed=distance/time=120/5=240m per sec

now, To west 60m in 1 sec so

speed=60 m per sec

Average Speed=distance travelled/time taken

=240+60/6=300/6=50m per sec

Average Velocity= displacement/time taken

=240-60/6=180/6=30m per sec
