What net is required to push a sofa with a mass of 59 kilograms so that it accelerates at 9.75 meters/second^2 (assume a flat, frictionless surface.)

Newton's 2nd Law of Motion:  Force = (mass) · (acceleration)

Do I need to go any further ?

I get  575.25 Newtons .

Oh !  Look at that !  Right there at the top, it says "Using Newton's Second Law".  This might have suggested to you that maybe you could solve the problem by using Newton's Second Law.

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )
