Question

A frog hops along a straight line path from point 'A' to point 'B ' in 10 seconds and then turns and hops to point 'C' in another 5 seconds . Calculate the average speed and average velocity of the grih for the motion between {1} A to B. {2} A to C { through B }. NOTE.........On a straight number line , 'A' lies on 7 , 'B' lies on -2 , 'C'
lies on 3 .

Answer 1

Answer:

1)9/10

2)13/15

Explanation:

1)Here A to B to length =9 unit and time taken 10 sec

so average speed =9/10 unit per sec.

2)Now A to C through B total length 13 unit and time taken total 15sec.

so average speed=13/15.
