1 point



20 ਮੀਟਰ ਪ੍ਰਤੀ ਸੈਕੰਡ (20 m/s)

2 ਮੀਟਰ ਪ੍ਰਤੀ ਸੈਕੰਡ (2 m/s)

ਇਹਨਾਂ ਵਿਚੋਂ ਕੋਈ ਨਹੀਂ (None of above)

10 ਮੀਟਰ ਪ੍ਰਤੀ ਸੈਕੰਡ (10 m/s)​

Answer 1

Explanation:

10 ਮੀਟਰ ਪ੍ਰਤੀ ਸੈਕੰਡ (10 m/s)

Answer 2

Given - Distance and time graph.

Find - Speed of the body using distance and time graph.

Solution - Speed of a body is calculated by the formula - distance/time. To calculate using graph, the change in distance with respect to change in time will be considered.

Taking initial distance 10 metre and final distance 20 metre. Taking intial time 5 seconds and final time 10 seconds.

Keeping the values in equation-

speed = (20-10)/(10-5)

speed = 10/5

speed = 2 metre/second.

Hence, the speed from distance time graph is 2 metre/second.
