Question

A body of mass 4kg is moving with a uniform velocity of 5m/s. It is acted upon by a force of 12N. The velocity

after 2s is (a) 11m/s (b) 6m/s (c) 10m/s (d) 11km/s​

Answer 1

Answer:

Gɪᴠᴇɴ:- M= 4 ᴋɢ

Fᴏʀᴍᴜʟᴀ:-

$a = \frac{v - u}{t}$

Solution:

$\frac{v - 5 }{2}$

F= 12 N

F= m× a

20 N = 4 kg × ( v - 5 )

5 = ( V- 5 )

Answer :- V = 10 m/ s
