A car with a mass of 30 kg rolls 35 meters to the right while experiencing an applied force of 200 N and a friction force that is 42 the magnitude of the applied force. The car takes 4.25 seconds to travel 35 meters. Calculate the power required to move the car. Final Answer Givens and Unknowns Equation and Substitution CFS: Drawn a freebody diagram Calculated the Friction force
Calculate net force Calculate work using w=Fd
State givens and unknowns
State the equation for net work Substituted values into the equation P=W/t
State the final answer with units​

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
