Given :-

  • Mass of the object is 3kg .
  • Its momentum is 1500kg m/s

To Find :-

  • Its velocity .

Solution :-

As we know that , the amount of motion contained in a body is called momentum . Mathematically ,


\sf\twoheadrightarrow Momentum = mass * velocity\\\\


\sf\twoheadrightarrow 1500kg\ m/s = 3kg * v\\\\


\sf\twoheadrightarrow v =(1500kg\ m/s)/(3kg)\\\\


\sf\twoheadrightarrow \underline{\underline{\blue{ velocity = 500m/s}}}

VELOCITY

Problem:

» An object whose mass is 3 kg is fired from an artillery cannon, giving it a forward momentum of 1050 kg•m/s . What is its velocity?

Answer:


  • \color{hotpink} \bold{500 \: m/s} \\

— — — — — — — — — —

— To calculate the velocity of a momentum, use formula:


  • \underline{ \boxed{ \tt v= (p)/(m) }} \\

where,

  • v is the velocity measured in meters per second (m/s)
  • p is the momentum in kg•m/s
  • m is the mass measured in kilograms (kg)

Solution:

Since the givens are 3 kg mass, and 1050 kg•m/s momentum, then...

Using the formula/equation above, we get


  • \tt \: v = (p)/(m)\\


  • \tt \: v = (1500 \: kg \cdot m/s)/(3 \: kg) \\


  • \tt v = \underline{ \boxed{ \blue{ \tt 500 \: m/s}}}\\


\therefore \sf Its \: velocity \: is \: \: \bold{500 \: m/s}
