Aconstant force is applied to an object, causing the object to
accelerate at 8.0 m/s2. what will the acceleration be if
a. the force is doubled?
b. the object’s mass is doubled?
c. the force and the object’s mass are both doubled?

The acceleration of the object if

a. The force is doubled → a = 16 m/s²

b. The object’s mass is doubled → a = 4 m/s²

c. The force and the object’s mass are both doubled → a = 8 m/s²

Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.

F = Force ( Newton )

m = Object's Mass ( kg )

a = Acceleration ( m )

Let us now tackle the problem!

Given:

a₁ = 8 m/s²

The force is doubled → F₂ = 2F₁

The object’s mass is doubled → m₂ = 2m₁

The force and the object’s mass are both doubled → F₂ = 2F₁ , m₂ = 2m₁

another example of kinetic energy would be,

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
