A constant force applied to A causes it to accelerate at 5 ms-2. The same force applied to B causes it to accelerate at 3 ms-2. What is the ratio of their masses mA :mB?

From Newton's second law of motion, the applied force is directly proportional to the acceleration produced or F=ma
The unit of force is newton in SI denoted by the symbol N.
Forces acting on a mass m1
with acceleration a1
and mass m2
with acceleration a2 are as given below.
m1 = a1/F =85kg.m2
=a2/F = 245 kg.
M=( 85+245)kg=(65)kg
Acceleration produced in M (when the two masses are tied together),
a=MF =655
=6 ms −2
