Usha swims in a 90 m long pool. She covers 180m in one minute by swimming from one end to the other and back along same straight path. Find average speed and velocity?
Answers
Answer:
:::Average Velocity = Displacement /Time Taken...
Average Velocity = Initial and final position are same. So, displacement will be zeroooo....
:::Average Speed = Total Distance traveled /Total time taken...
:::Average Speed = 180m/60s
:::Average Speed =3m/s...
Answer:
Average speed = 180m/s
Average velocity = 0m/s
Step-by-step explanation:
Total length of pool = 90m
Distance covered in one minute = 180m
Time = 1min
Average speed = Total distance covered
Total time taken
180
1
= 180 m/s
Displacement = 0(initial point and final point are same)
Average velocity = Displacement
Total time taken
0
1
=0m/s
