Answer:
Fn = 10 N
Step-by-step 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
