The mass of the go-cart in kilograms : 20 kg
Further explanation
Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
[tex]\large {\boxed {\bold {a = \frac {\sum F} {m}}}[/tex]
F = force, N
m = mass = kg
a = acceleration due to gravity, m / s²
Maybe the student's data are shown in the attachment
So, the mass of the go-cart :
[tex]\tt m=\dfrac{10}{0.5}=\dfrac{20}{1}=\dfrac{30}{1.5}=\dfrac{40}{2}=20~kg[/tex]
