Mass of the javelin is 16.25 kg.
Explanation for the problem.
Consider the given data:
Unbalanced force applied on the javelin, F= 130 Newtons
Acceleration gained by the javelin, [tex]a = 8m/s^{2}[/tex]
Write the expression for the unbalanced force based on the newtons second law.
[tex]F = m*a[/tex]
Here m is the mass of unbalanced forces.
Substitute the values in the above equation.
[tex]130 =m*8\\m =\frac{130}{8}\\ m = 16.25 kg[/tex]
Hence, the mass of the javelin is 16.25 kg.
