Question

a car traveling in straight line 360 m in 9 sec and 120 m in 3 sec and what is the average speed and average velocity​

Answer 1

ANSWER

$$(a)$$

Displacement from O to P=360m

Time taken from O to P=18sec

Velocity of car =TimeDisplacement

                         =18360m

Avg. Velocity of car (O to P)=20ms−1

Time taken from P to Q=6sec

Total time taken to move from O to P and back at Q, 

                            T′=16+6=24

Displacement from P to Q=240m

Average speed of car from P to Q=24sec240m

                                                            =10ms−
