Question

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 1

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 ,

$\sf\twoheadrightarrow Momentum = mass * velocity$

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

$\sf\twoheadrightarrow v =\dfrac{1500kg\ m/s}{3kg}$

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

Answer 2

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:

• $\underline{ \boxed{ \tt v= \frac{p}{m} }}$

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

• $\tt \: v = \frac{p}{m}$

• $\tt \: v = \frac{1500 \: kg \cdot m/s}{3 \: kg}$

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

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