Question

An astronaut throws a wrench in interstellar space. How much force is required to keep the wrench moving continuously with constant velocity?

Answer 1

the answer is a force is equal to zero

Answer 2

Answer: The force required to keep the wrench moving continuously in space is 0 N.

Step-by-step explanation:

Force applied on an object is defined as the product of the mass and acceleration of the object.

Mathematically,

`F=ma`

where, F = force applied

m = mass of the wrench

a = acceleration of the wrench

Acceleration is defined as the rate of change of velocity with respect to time. We are given, a wrench is moving with a constant velocity, so the acceleration of the wrench will be 0.

`a=(dv)/(dt)=0` (At constant velocity)

Putting values in above equation, we get:

`F=m* 0=0`

Hence, the force required to keep the wrench moving continuously in space is 0 N.
