B) 75 kg metre per second
C) 150 kg metre per second
D) 350 kg metre per second. ​

Answer 1

Answer:

$</p><p>\huge{\mathfrak{\underline{\underline{\pink{Answer:-}}}}}$

$\huge\boxed{50\:meter\:per\:second}$

$\color{red}{Given\:that:}$

• A body of mass 5 kg undergoes in speed.

• The speed changes from 30 meter per second to 40 meter per second.

$\color{red}{To\:Find:}$

• The momentum increased.

$\huge\boxed{Solution:}$

Mass = 5 kg

Initial Velocity = 30m/s

= 30 × 5 = 150 m/s

Final Velocity :- 40/sec.

$\boxed{Final \:momentum =pf=m×v}$

5 × 40 = 200

Change in momentum:-

$\boxed{pi-pf}$

200 - 150 = 50 kg m/sec.

$\huge\color{purple}{50\:kg\:m/sec}$
