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 : amount of force is required to push a sofa.

Explanation :

It is given that,

The mass of sofa, m = 59 kg

Acceleration,

According to Newton's second law of motion :

F = ma

m is the mass and a is the acceleration produced.

F = 575.25 Newtons

or

Hence, this is the required solution.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
