Posted below is a picture of a data table and a diagram of an experiment. In the experiment you rolled a marble down a ruler ramp off the end of a coffee table to observe projectiles and conservation of energy. You do 3 trials for each initial height. Each height is measured in meters. h= initial height of marble off of table Y= height of table off floor X= horizontal distance marble goes from edge of table to where it strikes the floor a) use the table to find information you need to solve for theoretical range and % of error in measured range.

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.

Please provide equations that you are using so I can follow along and learn how to do this. In Jamestown, NY, a coal power plan consumes coal at a rate of 80 tons/hr. When coal burns, it generates approximately 30,000 kJ for every kg of coal burned. The cooling course for the plant is the nearby Chadakoin River nearby and, by code, the power plant cannot reject more than 13.19 x 109 MJ into the river annually. Determine the maximum average power output of this plant and it's maximum thermal efficiency. To check your work, enter the efficiency, as a decimal, in the box provided.

As we explained in earlier chapters, the air resistance to the motion of a vehicle is something important that engineers investigate. The drag force acting on a car is determined experimentally by placing the car in a wind tunnel. The air speed inside the tunnel is changed, and the drag force acting on the car is measured. For a given car, the experimental data generally is represented by a single coefficient that is called drag coefficient. It is defined by the following relationship: F, where air resistance for a car that has a listed C, = drag coefficient (unitless) measured drag force (N) drag coefficient of 0.4 and width of 190 cm and height of 145 cm. Vary the air speed in the range of 15 m/s
