Question

An airplane accelerates on the runway at 3.0 m s2.  It has two engines which exert a total thrust of 3.0× 105N. What is the mass of this airplane?



Your Answer
A

0.5× 105 kg

Your Answer
B

2.0× 105kg

Your Answer
C

3.0× 105kg

Correct Answer
D

1.0× 105kg


Solution

The correct option is D

1.0× 105kg


Force = mass × acceleration

Thrust = mass × acceleration

Acceleration 3.0 m s2

Total Thrust = 3.0× 105 N

3.0× 105 N =  m× 3.0 m s2

m=1× 105 kg
