Answer:
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=a1F=85kg.
m2=a2F=245kg.
M=(85+245)kg=(65)kg
Acceleration produced in M (when the two masses are tied together),
a=MF=655=6 ms−2
D) Mass ×acceleraction
