22) Draw a diagram. This is similar to an example we did in class. a) Label the 3 forces acting on the mass.
b) Write down the (x, y) components of the electric force, Fe.
c) Write down the equations for F(x, y) = 0.
d) Solve the y equation for the magnitude of E (remember to
change gm - kg). First, solve for Ey then find E.
Ilsina x equation, solve for the tension T in the string.

Ababy stroller is a rest on top of a hill which is 10 m high. the stroller and baby have a mass of 20 kg. what is the potential energy of the baby and stroller?

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.
