The box leaves position x=0 with speed v0. the box is slowed by a constant frictional force until it comes to rest at position x=x1. find ff, the magnitude of the average frictional force that acts on the box. (since you don't know the coefficient of friction, don't include it in your answer.) express the frictional force in terms of m, v0, and x1.

Explain why the aperture of the spherical mirror should be small compared to the radius of curvature of the mirror.

Aria drove to the store, did some shopping, and then came home. during maria's trip, when was her displacement equal to zero?

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
