संकल्पना:
गणना:
दिया गया है कि
वस्तु 3 सेकंड में 23 m की यात्रा करती है।
वस्तु अगले 2 सेकंड में 15 m की यात्रा करती है।
वस्तु द्वारा तय की गई कुल दूरी = 23 + 15 ⇒ 38m
कुल समय = 3 + 2 ⇒ 5s
औसत गति = दूरी / समय
= 38/5 ⇒ 7.6 m/s
वस्तु की औसत गति 7.6 m/s या 7.6 ms-1
Concept:
Calculation:
Given that,
The object travels 23 m in 3 sec.
The object again travels 15 m in 2s.
Thus total distance travelled by the object = 23 + 15 ⇒ 38m
Total time = 3 + 2 ⇒ 5s
Average speed = distance/ time
= 38/5 ⇒ 7.6 m/s
The average speed of the object is 7.6 m/s or 7.6 ms-1
