Question

A 32 kg object has a momentum of 480 kg·m/s northward. What is the object's velocity?


A.
448 m/s

B.
15 m/s

C.
0.067 m/s

D.
15,360 m/s

Answer 1

Answer:=15v

Explanation:

Answer 2

The velocity of the object is 15 m/s option (b).

Given,

m = 32 kg

p = 480 kg m/s

To Find,

The velocity.

Solution,

Momentum refers to the amount of time it takes to bring a particle to rest when it is subjected to a constant force.

An object's momentum is equal to its mass times its velocity in terms of an equation.

Amount of mass accelerated by Momentum.

P is the symbol for momentum in physics. It is, therefore, possible to rewrite the above equation as p=mv. • Momentum is a vector quantity, i.e., it has both magnitude and direction.

Let's solve the question,

We will use the formula,

p = m × v

Now, we will put the value,

480 = 32 × v

v = 480 /32

On dividing, we get,

v = 15 m/s.

The velocity of the object is 15 m/s option (b).
