Question

f1=30Nandf2=10Nact on amass of 2kg if the cofficient of friction between the mass and the horizontal surface is 0.2 what is the acceleration of the mass​

Answer 1

The mass is moving with an acceleration of 13.299 m/s².

What is the straight forward meaning of acceleration?

The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. They are vector quantities, accelerations.

According to therefore mentioned statement,

the direction of the net force applied on an object determines its acceleration;

according to mentioned data;

F₁=30N

F₂=10N

Net force on object;

F=F₁+F₂

F=F₁y+F₂Cos30°(-x)+F₂ Sinx(-y)

F=3y+10×(√3/2)(-x)+10×(1/2)(-y)

F=ma

ma=-5√3/2(x)+25y

2a=-5√3x/2+25y

a=-5√3x+25y

magnitude(a)=√(-5√3/2)²+(25/2)²

     (a) =13.299m/s²
