a box is pushed with an applied force of 40 n parallel to the floor.it accelerated at 2.50 m/s2 to the right.a parallel applied force of 20n on the opposite side slowed down the motion of the box. neglecting friction.what is the mass of the box?
pa help po yung true answer please

Answer:
The force acting on an object is given by
where:
F = force
m = mass
a = acceleration
Solving for F
F = 20 N - 10 N
F = 10 N
Therefore, the mass of the box is 6.67 kg.
