Question

Calculate the momentum of a toy car of mass 200g moving with a speed of 5m/s.

Answer 1

Answer:

Given:  Momentum (p) = ?

                   Mass      (m)= 200g

       Speed/Velocity (v) = 5m/s  

Soln:   p = m/v

            p = 200g × 5m/s    

            p =  1000 g  

Explanation: You may remember that velocity is speed with direction, so if an object has a large speed, it also has a large velocity. Our momentum equation can be simplified even more by substituting the words for symbols: p = mv, where p is momentum, m is mass (in kg) and v is velocity (in m/s).

                         In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s. Newton's second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.

Answer 2

Answer:

we Know that,p=mv

P=200×5

P=1000gm/s
