Question

a body has weight 20N how much force is required to move it vertically upwards with an acceleration of 2m/s​

Answer 1

Given :-

• Weight = 20 N

• Acceleration = 2 m/s

To Find :-

• Force applied=?

Solution :-

As we know that,

F = ma

• F is the Force applied
• M is the Mass
• A is the Acceleration

According to the question,

F = 20 × 2

F = 40 N

Hence :-

Force applied is 40 N

Know More :-

• First equation of motion
• v = u + at

• Second equation of motion
• s = ut + ½at²

• Third Equation of motion
• v² - u² = 2as
