Engineering A car on a hill - power of motor problem
Would that Force be the force of the car and the velocity in v * sinθ is the unknown that I am trying to solve for? And would the equation for the gravitational potential energy be m*g*v*sinθ? I struggle with this stuff...- LippyKa16

Engineering A car on a hill - power of motor problem
So you would gain height at a speed of v*sinΘ? That would be the y component of velocity?- LippyKa16

Engineering A car on a hill - power of motor problem
Sorry, yes I did mean the weight of the car was at an angle. I was planning on adding the cosΘ term to all of the forces but that was unnecessary. Yes sorry, I meant dKE/dt = 0 because maximum velocity is a constant. The term d/dt (1/2*m*(1/2(u+v)t * sinΘ)) that I had was trying to...- LippyKa16

Engineering A car on a hill - power of motor problem
Homework Statement A car is traveling up a slope. Given that a(t) is constant at 1m/s^2, find the expression of motor power in time. Assuming that the maximum power of the car is 215kW, for how long can the car maintain such an acceleration? Mass of car (m) = 2000 kg The hill has a constant...- LippyKa16

Calculating Minimum Thickness of a Thin Film Using Interference Patterns
I wasn't too sure. Would that mean I would have to calculate the relevant wavelength through the film? Would that mean: λfilm = λ / n(benzene) (λ = 565 and n(benzene) = 1.5) λfilm = 3.77*10^-7 *EDIT* I realize the mistake I made, and I did need to calculate λfilm. The answer I got was...- LippyKa16

Calculating Minimum Thickness of a Thin Film Using Interference Patterns
Homework Statement A researcher measures the thickness of a layer of benzene (n = 1.50) floating on water by shining monochromatic light onto the film and varying the wavelength of the light. She finds that light of wavelength 565nm is reflected most strongly from the film. What does she...- LippyKa16
