Question

An object of mass 5 kilograms is moving across a surface in a straight line with a speed of 3.5 meters/second. What amount of force would be

required to keep the object in motion if you ignore the surface friction?
A.O newtons
B.17.5 newtons
C.3.5 newtons
D.5 newtons​

Answer 1

0 newtons

Step-by-step explanation:

F =MA

because constant motion means 0 acceleration.no changein velocity

F = 5 x 0m/s²

F = 0

Answer 2

Answer: The amount of force that is required to keep the object in motion is 0 N

Step-by-step explanation:

Force is defined as the push or pull on an object with some mass that causes change in its velocity.

It is also defined as the mass multiplied by the acceleration of the object.

Mathematically,

`F=ma`

where,

F = force exerted on the object

m = mass of the object = 5 kg

a = acceleration of the object =
`0m/s^2` (Speed is constant)

Putting values in above equation, we get:

`F=5kg* 0m/s^2\\\\F=0N`

Hence, the amount of force that is required to keep the object in motion is 0 N
