Question

speed of the rockets?​

Answer 1

Approximately,7800m/s (28000km/h, 17000mph)

Answer 2

Answer:

Due to their high exhaust velocity—2,500 to 4,500 m/s (9,000 to 16,200 km/h; 5,600 to 10,100 mph)—rockets are particularly useful when very high speeds are required, such as orbital speed at approximately 7,800 m/s (28,000 km/h; 17,000 mph).
