Answer to Question #289104 in Mechanics | Relativity for hewnciewn

Question

A 2.96 kg particle has a velocity of (3.00 i hat - 4.06 j) m/s.

(a) Find its x and y components of momentum.

Answer 1

Let the velocity vector be:

$\mathbf{v} = (3, 4)\space m/s$

By definition, the momentum is:

$p=mv=2.96⋅(3,4)=(7.88,11.84) kg⋅m/s$

X components= $7.88kg⋅m/s$

Y components =$11.84kg⋅m/s$
