Question

Define S.I unit of force . A force of 2newton acting on a body changes its velocity uniformly from 2m/s to 5m/s in 10 sec calculate the mass

Answer 1

HEY BUDDY..!!!

HERE'S THE ANSWER..

_____________________

♠️ The SI unit of force is Newton ( N ) or Kg m / s^2

______________________

✔️ First we'll note the data from question

⏺️F ( force ) = 2 N

⏺️u ( initial velocity ) = 2 m / s

⏺️v ( final velocity ) = 5 m / s

⏺️t ( time ) = 10 s

⏺️ a ( Acceleration ) = ?

⏺️m ( mass of body ) = ?

♠️ We know Acceleration is change in velocity with respect to Time , i.e

✔️ a = ( v - u ) / t

=> a = ( 5 - 2 ) / 10

=> [ a = 3 / 10 m / s^2 ]

♠️ Now we know { F = m × a }

=> F = m × a

=> m = F / a

=> m = 2 / ( 3 / 10 )

=> m = 2 × 10 / 3

=> [ m = 20 / 3 kg ]✔️✔️



♠️ Mass of body is 20 / 3 kg

Answer 2

Heya!!

--------------------------------

SI unit of force is Newton (N).

1N is force which produce an acceleration of 1 m/s^2 in a body of mass 1kg.

Since F = ma

=) 2 = m (v-u) /t

=) 2 = m(5-2/10

=) 2 = m*3/10

=) 2*10 / 3 kg = m

=) 20/3 kg

Hope it helps uh :)
