Answer 2

Answer:

8 kg

Explanation:

Given,

Force ( F ) = 8 N

Initial velocity ( vi ) = 5 m / s

Final velocity ( vf ) = 7 m / s

Time ( t ) = 2 s

To find : Mass ( m ) = ?

Acceleration ( a ) = ?

Formula : -

a = ( vf - vi ) / t

= ( 7 - 5 ) / 2

= 2 / 2

a = 1 m / s²

To find mass, the formula to be used is,

F = ma

m = F / a

= 8 / 1

m = 8 kg

Therefore, the mass of the particle is 8kg.
