Question

A body of 10 kg mass is moving with 15 m/ s in 10s it's velocity increases to 25 m/ s find change in momentum And find force required for this change

Answer 1

Answer:

100 kg m/s & 10 N

Explanation:

• Momentum = mass × Velocity

Change in momentum = m(v - u)

= 10 kg × (25 m/s - 15 m/s)

= 10 kg × 10 m/s

= 100 kg m/s

Force = Change in momentum / Time taken

= (100 kg m/s) / (10 s)

= 10 kg m/s²

= 10 N

Answer 2

$\huge{\underline{\underline{\mathfrak{Answer}}}$

Momentum = mass × Velocity

Change in momentum = m(v - u)

= 10 kg × (25 m/s - 15 m/s)

= 10 kg × 10 m/s

= 100 kg m/s

Force = Change in momentum / Time taken

= (100 kg m/s) / (10 s)

= 10 kg m/s².
