The brakes are applied to a moving van, causing it to uniformly slow down. while slowing, it moves a distance of 40.0 m in 7.70 s to a final velocity of 1.80 m/s, at which point the brakes are released. (a) what was its initial speed (in m/s), just before the brakes were applied? m/s (b) what was its acceleration (in m/s^2) while the brakes were applied? (assume the initial direction of motion is the positive direction. indicate the direction with the sign of your answer.) m/s^2

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons
