Respuesta :

Mass of the system is 25.2 kg
Calculation:

F=ma

m = F/a  where a = m/t^2

a=2.3/(1.3)^2 = 1.36 m/s^2

m=34.3/1.36

m=25.2 Kg

Answer:

m = 12.6 kg

Explanation:

As we know that it covers total distance of 2.3 m in 1.3 s

so we will have

[tex]v_i = 0[/tex]

[tex]d = 2.3 m[/tex]

[tex]t = 1.3 s[/tex]

now we can use kinematics to find the acceleration

[tex] d = v_i t + \frac{1}{2}at^2[/tex]

[tex]2.3 = \frac{1}{2}a(1.3^2)[/tex]

[tex]a = 2.72 m/s^2[/tex]

Now we can use Newton's law

[tex]F = ma[/tex]

[tex]34.3 = m(2.72)[/tex]

[tex]m = 12.6 kg[/tex]
