Question

An object of mass 2 kg is sliding with a velocity of 4 m per sec the regarding force necessary to stop the object in one second???

Answer 1

Answer:

Given, mass m = 2 kg, velocity v = 4 ms-1

As the object is moving with a constant velocity, so the acceleration of the object is zero.

a = 0

According to the property of inertia, if there is no external force acting on the body, then body remains as it is i.e., if the body is at rest, and if it is in motion remains in motion.

F = ma

F = 0 N

Answer 2

Answer:

0 Newton

Explanation:

Given, mass m = 2 kg

velocity v = 4 ms-1

As the object is moving with a constant velocity i.e., 4 ms-1 so the acceleration of the object is zero

i.e.,

a = 0 and according to the property of inertia if there is no external force acting on the body, then body remains as it is i.e., if the body is at rest, remains and if it is in motion remains in motion.

From newton's Ist law of motion, since there is no external force acting on the object it will remain in its original state of motion. Hence, zero force is required to keep the object moving with constant velocity, correct answer is 0 N
