Question

A body of mass 25 kg has a momentum of 125 kg.m/s. Calculate the velocity of the body.

Answer 1

★ Given:-      

• ➪ Mass of the body = 25 kg
• ➪ Momentum = 125 kg.m/s

★ To Find:-        

• ➪ Velocity of the body

★ Solution:-      

Here, we have the mass of the body is 25 kg and momentum of 125 kg.m/s  

So, to find out the velocity we will use the formula of momentum.  

• The formula of momentum is p = mv

Where,    

• ➳ Momentum = P
• ➳ Mass = m
• ➳ Velocity = v

                          ____________

♡ Applying the formula of momentum, ♡

• ➼ Momentum = Mass × Velocity
• ➼ Momentum (p) = Mass (m) × Velocity (v)
• ➼ 125  = 25 × velocity
• ➼ Velocity = 125/25
• ➼ Velocity =  25/5
• ➼ Velocity = 5 m/s

. ° . Thus, velocity of the body is 5 m/s.

                      __________

Answer 2

★ Given:-    

• ➢ Mass = 25 kg

• ➢ Momentum = kg.m/s

★ To find:-      

• ➢ Velocity

★ Calculations:-    

• ➝ Momentum = Mass × Velocity

• ➝ 125 = 25  × Velocity

• ➝ 125/25 = Velocity

• ➝ 25/5 = Velocity

• ➝ 5 m/s = Velocity

. ° . The velocity is 5 m/s.
