A baseball with a mass of 139 g is thrown horizontally with a speed of 39.4 m/s (88 mi/h) at a bat. The ball is in contact with the bat for 1.10 milliseconds and then travels straight back at a speed of 45.0 m/s (101 mi/h). Determine the average force (in N) exerted on the ball by the bat. Choose the direction of the incoming ball to be positive. (Indicate the direction with the sign of your answer.)

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.

Asmall 12.00g plastic ball is suspended by a string in a uniform, horizontal electric field with a magnitude of 10^3 n/c. if the ball is in equilibrium when the string makes a 30 ° angle with the vertical, what is the net charge on the ball?
