What net force is required to push a sofa with a mass of 59 kilograms so that it accelerates at 9.75 meters/secondÆ? (Assume a flat, frictionless surface.)

A6.1 Newtons
B59 Newtons
C5.8 x 10^2 newtons
D6.0 x 10^2 newtons

Verified Answer :

Answer : \(F=5.8\times 10^2\ Newtons\) amount of force is required to push a sofa.

Explanation :

It is given that,

The mass of sofa, m = 59 kg

Acceleration, \(a=9.75\ m/s^2\)

According to Newton's second law of motion :

F = ma

m is the mass and a is the acceleration produced.

\(F=59\ kg\times 9.75\ m/s^2\)

F = 575.25 Newtons

\(F=5.75\times 10^2\ Newtons\)

or

\(F=5.8\times 10^2\ Newtons\)

Hence, this is the required solution.
