A jumbo jet has a mass of 100,000 kg. The thrust for each of its four engines is 50,000 N. The acceleration of the jet when taking off is A)0.5 m/s². B)1 m/s². C)2 m/s². D)4 m/s². E)none of the above

Question

Quizplus · Accepted Answer

The total thrust produced by all four engines in the jumbo jet is:
4 × 50,000 N = 200,000 N

The acceleration of the jet is given by the formula:
a = F/m
where F is the net force on the jet and m is its mass.

In this case,
F = 200,000 N - the force generated by the four engines
m = 100,000 kg - the mass of the jet

a = (200,000 N) / (100,000 kg) = 2 m/s^2

Therefore, the acceleration of the jumbo jet when taking off is 2 m/s^2, which corresponds to answer choice C.
