Q1. A driver in a car travelling at a speed of 58.0 mi/h sees a deer 126 m away on the road. Calculate the minimum constant acceleration that is necessary for the car to stop without hitting the deer (assume that the deer does not move in the meantime).

Q2. Two 2.0 kg plastic garbage cans are sitting 2.6 meters apart on a sticky classroom floor (coefficient of static friction μs = 0.40). They are not moving. If the first one has a charge of 10 μC, find (a) most negative possible charge and (b) most positive possible charge for the other garbage can. Suppose that charges can be represented as point charges located at the cans' centers.
