2. Suppose your phone's battery has a capacity of 2500 mAh and a potential difference of 3.7 V. What is the amount of charge, in C (coulombs), that is stored in your smartphone battery when it's fully charged? Charge - 9000 3. Smartphone chargers are usually labeled with their current output in A (amps). Suppose your charger delivers a current of 1.1 A. If your phone's battery is completely drained, how long will it take to fully charge the battery using your charger? Charging time - 2.27 v hours 4. Smartphones are advertised with a certain amount of "talk time", i.e., how long the phone's battery will last if you are making a call. If your phone is advertised with 24 hours of talk time, what is the average current coming from your phone's battery while making t Average current - A 5. What is the average power output of your phone's battery while you're making a call? Average power - w

This activity focuses on the concept of torque and Second Condition of Kquilibrium. Torque is the rotational courterpart of force For a system to be in equilibrium, the net torque must be equai to zero.

Context We want to calculate the time that will elapse before two vehicles collide. The two vehicles go through an uniformly Accelerated Motion (UAM). Constraints Vehicle A is initially at the origin and moving at constant speed. Vehicle B initially lies on the positive side of the x axis and has an initial speed of zero. Modelization Build the model that calculates the moment of collision between the two vehicles. Then test your model using the following values: The vehicle A's initial speed is 3.7 m/s The initial position of vehicle B is 213 meters The vehicle B's acceleration is -2.01 m/s^2

a. d. Always come back to the example of the tennis ball to remember on which direction you need to apply the coefficient of restitution. Because the bounds are lower and lower and the coefficient of restitution is less than 1, you apply the coefficient of restitution on the axis normal to the plane of contact. For the tennis ball the plane of contact is the floor and the axis normal to the plane of contact is 2. O bigger O lower line 93 impact O the same The components of the velocity on x and y are the same and the component of the velocity on z is after impact. - x 3. plane contact You can also find the line of impact using this definition: The line of impact is a line through the But this definition is hard to use when only one particle collides into a surface. This definition is great to use when 2 balls collide together as this example: O mass centers of the colliding particles. O geometric centers of the colliding particles 10 m/s b.
