Find the y-component of this vector:73.3,12.0m. Remember, angles are measured from the +x axis.

Rainbow [258]

Answer:

11.5 meters

Explanation:

73.3°, 12.0m

The y-component is the magnitude of the vector times the sine of the angle measured from the +x axis.

y = 12.0 sin (73.3°)

y = 11.5

The y-component is 11.5 meters.

Answer:

$3 m/s^{2}$

Explanation:

ΣF=ma

The two forces at play are the force applied and the force due to friction. As they are opposing forces set the direction being pushed as the positive in the x direction. the equation you come out with is 60 - 15=(15)A (we know mass to be 15kg). Solve for 3 m/s^2.
