Electro, one of Spiderman's recurring enemies, is being confronted by police. One officer loses his cool and shoots his gun, sending a copper-sheathed bullet weighing 160 grams at Electro with a velocity of 200 m/s. The officer is 100 meters away from Electro when the gun discharges. a) Ignoring the vertical motion of the bullet (that is, ignoring gravity), what acceleration does the bullet have to undergo in order to stop just before striking Electro? b) Imagine that Electro can generate an electric field of 1.0 x 106 N/C. As the bullet travels across that 100 m distance, what is the change in electric potential? (Assume the electric field is uniform and constant over that space.) c) What charge must appear on the bullet in order for him to stop it in time? d) How many electrons must be removed in order to create that charge?

One day, your Math professor takes a video of Chico the Dog doing something adorable. They then post it on TikTok. After 3 minutes, the total number of views is 2,519. After 7 minutes, the total number of views is 3,426. A) Assuming the number of views grows according to an exponential model, write a formula for the total number of views (V) the video will have after t minutes. Round any decimal answers to at least 3 decimal places. In the box given below, upload a copy of your work for this problem. This work should show how you used algebra (i.e. solving equations) to find the formula. B) Based on your answer from part (a), find the doubling time for the number of views of the video. Round any decimal answers to at least 3 decimal places. To solve this problem, you must first set up an equation. Use the box below to explain what your setup is and why you set up the equation the way that you did. Be sure to describe what numbers you put into your equation and why each is put into the spot that it is. In the box given below, upload a copy of your work for this problem. This work should show how you used algebra (i.e. solving equations) to find the answer. C) How many views will the TikTok have after 90 minutes? Round any decimal answers to at least 3 decimal places.
