A143-g baseball is flying through the air with a speed of 180 km/hr just after it is hit by a bat. if its velocity is at an angle of 37º above the horizontal and 22º north of east, find its momentum in unit-vector notation. define east as x and north as y

To solve the problem it is necessary to apply the concepts related to the conservation of linear Moment, that is to say

Where,

m = Mass

v = Velocity

P = Linear momentum

For the given data we have to:

The components of this force would be given by,

According to the definition given at the end of the problem, this component corresponds to that expressed for x and y.

Applying the previous equation we have,

Note: The component at this direction must also decomposed

The mass is 143g=0.143kg, then:

Therefore the final vector is:
