43.1N
Step-by-step explanation:
this question involves the application of the use of the equations of motion and the newton's law of motion
the parameters are
initial velocity u = 0
distance (s)= 12
mass (m)=5.5kg
t=1.75s
a= acceleration
S= ut + at²
12= (0×1.75) + ( × a × 1.75²)
12= 0 + (1.53125 × a)
12 = 1.53125 × a
a = 12÷1.53125
a= 7.8367m/s²
F=m × a
=5.5 × 7.8367
=43.10N
