Question

a force of 10 kgs weight acting on a certain mass for 2 seconds day with a velocity 10 metre per second what is the mass in kg​

Answer 1

Answer:

It has to be mentioned whether the body is already in motion or at rest.

If it is assumed that the body is at rest, then according to linear one dimensional kinematical formula (v = u + at), where v is final velocity, u is initial velocity, a is accelaration, t is time, we get, (10 = 0 + 2a), hence a = 2

Now, Force = mass*accelaration,

which implies (10 = mass*2)

So, required mass = 5kg.
