A jumbo jet has a mass of 100,000 kg. The thrust for each of its four engines is 50,000 N. What is the jet's acceleration in meters per second per second when taking off?
A) 2
B) 4
C) 0.25
D) 1
E) none of these

Question

Quizplus · Accepted Answer

The total thrust is 200,000 N (50,000 N per engine x 4 engines). Using Newton's second law, F = ma, the acceleration a = F/m = 200,000 N / 100,000 kg = 2 m/s².
