EXPERIMENT ONE The purpose of this experiment is to use the given data to plot graphs and determine the experimental values of the acceleration due to gravity. A. The table below shows data taken in a free-fall experiment. Measurements were made of the distance fall (y) at each of four precisely measured times. Complete the table. Round off to same number of decimal places, even if you carry extra digits during your intermediate calculations. Time, ly,(m) y,(m)ly,(m)ly,(m)ly.(m)yt (s') (s) 0.00 0.00 0.00 0.00 Jo.00 0.00 0.50 1.0 1.4 1.1 1.4 1.5 0.75 2.6 1.00 4.8 8.2 3.2 2.8 2.5 3.1 4.4 5.1 4.7 4.8 1.25 7.9 7.5 8.1 7.4 B. The equation of motion for an object in free fall starting from rest is y = ½ gt, where g is the acceleration due to gravity. This is the equation of a parabola, which has the general form y = ax². Convert the curve to a straight line by plotting i versus t?. That is, plot the square of the time on the horizontal axis. Determine the slope of the line and compute the…

You need to guide a robot from the red dot on the left to the green dot on the right, avoiding the blue walls along the way. units To do this, you must feed it a series of commands of the form "turn degrees and move forward". Angles are measured in degrees, with positive angles turning counterclockwise, and negative angles turning clockwise. All turns are relative to the robot's current direction. The grid marks 1 unit squares. From the red starting dot, with the robot facing directly to the right, issue your commands: (all commands should be given as decimal values) Move 1: Turn 9 Move 2: Turn Move 3: Turn Move 4: Turn degrees and move degrees and move degrees and move degrees and move units forward units forward units forward units forward

Apparatus When James Watt invented his steam engine, he was asked how many horses the engine could replace. To find out, he built a rope-and-pulley device with which he could measure the time it took a horse to lift var- ious weights. Stairs, Stopwatch, Meter stick. Theory Consider the (rather crude) person climbing a flight Watt defined horsepower as the power a horse can produce steadily for a sustained period of time.

Activity 5: Check for Understanding (5 mins) Student Engagement (SE) Think-Pair-Share Solve the problem. 1. You are working as an expert witness for the defense of a container ship captain whose ship ran into a reef surrounding an island. The captain is being charged with intentionally running the ship into the reef. In discovery, the following information is correct: The ship was traveling at 2.5 m/s toward the reef when a mechanical failure caused the rudder to jam in the straight-ahead position. At that point in time, the ship was 900 m from the reef. The wind was blowing directly toward the reef and exerting a constant force of 9.00 x 10³ N on the boat in a direction toward the reef. The mass of the ship and its cargo was 5.50 x 107 kg. During the preparation for the trial, the captain claims that without control of the direction of travel, the only choice he had was to put the engines in reverse at maximum power, such that the total force exerted by the frictional drag force of…

Keeping the total mass constant 1.  Look at the data: as the net force increased, what happened to the acceleration? Did it increase, decrease or stay constant? 2.  Did a change in the net force produce a change in acceleration by the same factor? Do your results agree with Newton’s 2nd Law? 3.  Make a plot of Net Force vs. Experimental Acceleration and draw the best fitting line.

X Y show all your steps and write your final answers in a sentence. Please use g = 9.80 for each of these questions to increase precision. Therefore all answers will have 3 significant digits. There is no friction. The mass of X is 7.34 kg and the mass of Y is 1.82 kg. The incline of the ramp is 44.7 degrees. a) Calculate the acceleration of the system. Include the direction. b) Calculate the tension in the rope connecting the X and Y blocks. c) Calculate the new mass of block Y, keeping block X the same, that acceleration is zero. d) If there was friction, then there would be a range of masses block Y can be,such that the acceleration would be zero, not just one number. Explain why this is the case.

How do the values of µs compare to the values of µk? (Of course, you can only compare them for the same pairs of materials.)   Is the relationship between µs and µk what you expected? Explain.   What are three reasons why friction is needed?   Does the coefficient of friction change with mass?   How can we reduce friction?   What would happen if there was no friction?   Does frictional force depend on mass?   What are 3 factors that affect friction?   Is friction affected by surface area?   Can humans live without friction?   Why is the coefficient of friction less than 1? Explain.
