With what acceleration did the rocket move if its speed changed from 4 to 6 km / s and at the same time a movement of 1000 km was made? What is the time during which this movement is completed?
Solution:
1 000 000 = 4000t + at2 / 2
at = v – v0 = 2000
1,000,000 = 4000t + 1000t
1 000 000 = 5000t
1000 = 5t
t = 200 s
200a = 2000
a = 10 m / c2
Answer: 10 m / s2; 200 s
