Write a hypothesis about the effect of the angle of the track on the acceleration of the cart. Use the "if ... then
.. because ..." format and be sure to answer the lesson
question: "How does an object's position and velocity
change as the object accelerates?”

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply

Automobile fuel efficiency is often measured in miles that the car can be driven per gallon of fuel (mpg). heavier cars tend to have lower fuel efficiencies (lower mpg ratings). which variable (weight or fuel efficiency) is most naturally considered the explanatory (predictor) variable in this context?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
