5. Annie drags her little red wagon with a mass of 5.00 kg, up a hill that has an angle of elevation of 30.09. She applies the force of 150 N parallel to the incline. Assume that
the wagon starts from rest at the bottom of the hill, and neglect friction (4 points)
a) What is the value of the acceleration of the wagon?

Explanation:

Given

mass of wagon m=5 kg

elevation

Sin component of weight will oppose the applied force therefore we can write

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
