Newton's third law of motion. Because you are pushing the water backwards which will push you forwards
Answer:
a)5m b)5secs c) 10secs
Explanation:
a) maximum height H = u²/2g
Given u = 50m/s
g = 10m/s²
H = 10²/20
H= 5m
maximum height reached by the rocket is therefore 5m
.b)Time it takes the rocket to reach its maximum height is Tmax = U/g
Tmax = 50/10
Tmax = 5seconds
c) How long the rocket spent in the air is the time of flight T
T = 2U/g
T = 2×50/10
T = 100/10
T = 10seconds
Σ/ε
σ = F/A
ε = ΔL/L
F = force
A = area
L = lenght
ΔL = |old lenght - new lenght|
