You can tell by making sure that the lights are unplugged and tighten lights then plug it in if I didn't work it's burnt :) hope it works
Answer:
The thrust of the jet engine is 4188.81 N.
Explanation:
Given that,
Speed = 260 m/s
Rate in air= 53.3 kg/s
Rate of fuel = 3.63 kg/s
Relative speed = 317 m/s
We need to calculate the rate of mass change in the rocket
Using formula of rate of mass
Put the value into the formula
We need to calculate the thrust of the jet engine
Using formula of thrust
Put the value into the formula
Hence, The thrust of the jet engine is 4188.81 N.

Answer:
4×10⁴ seconds
Explanation:
Assuming you have a calculator on hand, inputting 300 ÷ .0081 give should give you 37037.0370...
In scientific notation, that number would be 3.70370370...×10⁴ and when taking into account the rounding rules for significant figures, the answer is 4×10⁴ seconds.
Answer:
31.28m/s
Explanation:
We can use the third key equation of accelerated motion
Δd = viΔt+1/2aΔt^2
subtitute in the values we know
41.6 = vi(1.89)+1/2(-9.8)(1.89)^2
41.6 = vi(1.89) - 17.52
59.12 = vi(1.89)
vi = 31.28
