Question

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.)

A. 6.1 Newtons
B. 59 Newtons
C. 5.8 x 10^2 newtons
D. 6.0 x 10^2 newtons

Answer 1

Answer :
`F=5.8* 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* 9.75\ m/s^2`

F = 575.25 Newtons

`F=5.75* 10^2\ Newtons`

or

`F=5.8* 10^2\ Newtons`

Hence, this is the required solution.
