Question

An empty plane whose mass is 30, 400Kg has a maximum takeoff acceleration of 1.20m/s2 . What is its maximum acceleration when it is carrying a load of 8200Kg?​ Ignore friction.

Answer 1

Answer:0.95 m/s2

Explanation: The thrust of the engines, calculated for weight

F=ma=30400·1.2=36480\text{ N}.F=ma=30400⋅1.2=36480 N.

The acceleration with the load is

aL=\frac F{m+M}=\frac{36480}{30400+8200}=0.95\text{ m/s}^2.aL​=m+MF​=30400+820036480​=0.95 m/s2
