Question

A body has weight of 20 N How much force is required to move it vertically upward with an acceleration of 2ms-2 ?

Answer 1

Answer:

Explanation: To solve for that acceleration, you need to find the object's mass by dividing its weight by the acceleration of gravity. Then, Newton's law,

F = m*a

 

The end to solve for that acceleration, we need to find the object's mass by dividing its weight by the acceleration of gravity. Then, Newton's law,

F = m*a

 

Answer 2

QUESTION:-

A body has weight of 20 N How much force is required to move it vertically upward with an acceleration of 2ms-2 ?

GIVEN:-

• A body has weight of 20 N
• Acceleration produce 2 m/s²

TO FIND:-

Force required

EXPLANATION:-

Using newton's 2nd law formulae

$\boxed{\bf\;F=ma}$

Where

F=force

m=mass

a=acceleration

So let's put the data of the question in the formula for get required force

Mass:-

10 N =1 kg

20 N =2 kg

So mass=2 kg

Acceleration= 2 m/s²

F=ma

F=2×2

F=4 N

So the force required will be 4 N
