The x-component is 8 m/s east; the y-component is 14.5 m/s North. (a) What is the value of the resultant vector? (b) What is the angle of the resultant vector?

Explanation:

Given that,

The x-component is 8 m/s east and y-component is 14.5 m/s North.

(a) As both x and y components are perpendicular to each other. Their resultant is given by :

(b) Let is the resultant vector. So,

Hence, the resultant is 16.56 m/s and the angle of the resultant vector is 61.11 degrees.

we need to know the time interval during which the force acts. impulse of force = momentum change
