Physical Science 1. State how constant velocity and constant acceleration are different. 2. State how constant speed and constant velocity are different. 3. In which cases is there acceleration. (Choose any correct answer or answers) A. Slowing down for a squirrel B. Stopped at a traffic light C. Increasing speed after on the freeway D. Traveling on a straight, flat road and maintaining 25 mph E. Maintaining 30 mph through a curve in the road F. Slight alterations in directions (N, S, E, W) as you maintain 65 mph on the freeway 4. Large ships carry several megatons of cargo. A cargo ship traveling East on the ocean at 40 kph takes 34 minutes to come to a complete stop. A. Calculate the average acceleration B. State the direction of the acceleration (North, South, East, or West) as the ship slows C. Calculate the distance the ship travels as it goes from 40 kph to 0 kph D. Is the ship accelerated downward by gravity? (Yes or No) 5. A ball is thrown straight down toward the ground with an initial speed of 12 m/s from the top of a tall building. Assume there is no air resistance a. What is the rate of acceleration once the ball leaves my hand? b. What is the speed of the ball 0.5 seconds after leaving my hand
