Question

what is the acceleration of a cabinet of mass 45 kg if Jake and Ted push it by applying horizontal force of 25 Newtons and 18 Newtons respectively in the same direction

Answer 1

Net force = (mass) x (acceleration)

Acceleration = (net force) / (mass)

Net force = (25 newtons + 18 newtons - friction force)

Net force = 43 newtons - friction force

Acceleration = (43 newtons - friction force) / (43 kg)

Answer 2

F(net) = ma, so
Acceleration= net force / mass
Net force = 25 N + 18 N = 43 N
Mass = 45 kg
Acceleration = 43 N / 45 kg = 0.96 m/s^2
