The force on the object will be 12 N.
We have a moving object.
We have to determine the force on object when the acceleration of the object becomes 2 m/s².
What is the need of Force in real Life? How is it calculated ?
Force is necessary to bring around a change in the state of the body. Either from rest to motion or motion to rest. It can be calculated using the formula-
Force (F) = mass (m) x acceleration (a)
According to the question -
When a force of 42 N acts on the object, then using the formula of force -
F = m x a
42 = m x 7
m(Object) = 6 Kg
When the acceleration of the object becomes 2 m/s², then -
F = m(object) x a
F = 6 x 2 = 12 N
Hence, the force on the object will be 12 N.
