Q1. You're driving down the highway late one night at 20 m/s while a deer steps onto the road 44m in front of you. Your reaction time before stepping on the brakes is 0.50 s, and the maximum deceleration of your car is 11m/s^2 .How much distance is between you and the deer when you come to a stop?
Q2. A man drags a table 4.30 m across the floor, exerting a constant force of 55.0 N, directed 26.0° above the horizontal.
