An object with a mass of 2.0 kg is accelerated at 5.0 m/s/s. the net force acting on the mass is

Fn = 10 N

Explanation:

Newton's second law:

∑F = m*a Formula (1)

∑F : Net force acting on the mass  or algebraic sum of the forces in Newton  (N)

m : mass s (kg)

a : acceleration  (m/s²)

Data

m = 2.0 kg : mass of the object

a = 5.0 m/s² : acceleration of the object

Calculation of the net force (Fn) acting on the mass

We apply the formula (1)

∑F = m*a, ∑F = Fn

Fn = m*a

Fn = (2.0 kg)* (5.0 m/s²)

Fn = 10 N
