    I.ESSAY QUESTIONS
    1.What us the difference between static equilibrium and dynamic equilibrium? Explain your answer fully.

    2.State and explain and the conditions for translational equilibrium.

    3.What horizontal forces act on a car traveling westward on a level road at a constant speed of 20m/s?Explain your answe fully.

    II.WORD PROBLEM(VECTOR DIAGRAMS ARE NEEDED)

    1.A 1500-kg car is stationary(not moving) on a ramp that makes an angle of 35(degree) with the horizontal.

    a)Draw a vector diagram showing all the forces acting on the car> label and identify(name) all these forces.(note. ineed the vector very importantly.)

    b)What is the magnitude of the force parallel to the ramp that keeps the car stationary?(Show complete solution)

    2.A child weighing 200 N swings on a rope. If the child is to be held such that the rope is at an angle of 37(degree) with the vertical, what horizontal force must act on the child?

    a)Draw a vector diagram showing all the forces acting on the child. Label and identufy(name) all these forces.

    b)What is the manitude of the horizontal force acting on the child?(Show complete solution.)


    Name of Forces:example:
    normal force
    frictional
    etc.

    I have answered the number 3-6 but its taking me a hard time to solve for the 1 and 2...

    Welcome to the Forums,

    Do you have any thoughts on any of the questions? In addition, I would advise against posting a personal e-mail address on forums, it leaves you exposed to spam and personal attacks via e-mail.
