Use the following information for Questions 7, 8 and 9: t3 +y* = 3t –7. 7. The derivative of the left-hand side of the equation with respect to t is: 3. The derivative of the right-hand side of the equation with respect to t is:

From your graph of T2 vs. l, determine a value for g.

3. Assuming that the variables a, b, c, d and f are scalars, write MATLAB statements to compute expressions. Test your statements for the values a = 1.12, b = 2.34, c = 0.72, d = 0.81, f= 19.83 and display the following а. X = 14

I need these three parts answered, if you are unable to answer all three parts please leave it for another tutor to answer, thank you.

Q1. The image below shows an example of "absolute dependent motion analysis", where the motions of two objects depend on each other, and the goal is to find the relations in their motions (i.e., in their positions, velocities, and accelerations). Please put the suggested steps of analysis in the correct order. VA A B VB Differentiate the entire equation with respect to time, and extract the relation in velocities. Repeat for acceleration if needed. Set up a coordinate (s) along the direction of motion from a fixed point (O) or a fixed datum line. Represent the positions of the objects respectively. In some cases intermediate objects need to be considered too and their positions need to be represented as well. Recognize the constant length(s) and find the depending geometric relations between the position variables.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

Two students are playing catch outside. One throws the ball too high and overshoots his friend, hitting the streetlight - whoops! What is the height hB of the ball when it passes over player B? VA В hB ho A ha ha * dBc dAB dAB = 27 ft h4 = 8 ft dBC = 4 ft h. = 10.7 ft 0 = 29° What is the magnitude of v4? Enter your answer correct to two 2 decimal places. ft/s VA
