Answer:
1.275 m
Explanation:
Let the maximum height reached be h.
Here initial velocity, u = 5 m/s
Final velocity, V = 0
Use third equation of motion
V^2 = u^2 + 2 g h
0 = 25 - 2 × 9.8 × h
h = 25/19.6 = 1.275 m
1N=1kg•m/s^2 so the answer is 3N
They will rise to the 2nd layer of the atmosphere where the temperature decreases by a lot and then they will blow up
