2. Calculate the average power output needed from an external interaction to cause a 1,150-kg car to climb a $3^\circ$ slope at a constant speed of 30.0 m/s while encountering wind resistance of 500 N. Note: Unlike friction, wind resistance can be treated like any other force that does work on the center of mass displacement of the object. The force directly opposes the direction of motion.

Calculate the power output needed for a 950 -kg car to climb a $2.00^{\circ}$ slope at a constant 30.0 $m/s$ while encountering wind resistance and friction totaling 600 $N$ . Explicitly show how you follow the steps in the Problem- Solving Strategies for Energy.
Calculate the power output needed for a $950-\mathrm{kg}$ car to climb a $2.00^{\circ}$ slope at a constant $30.0 \mathrm{m} / \mathrm{s}$ while encountering wind resistance and friction totaling $600 \mathrm{N}$
Power: a car climbs up an incline at constant speed) This problem is similar to an example in lecture. A 810-kg car climbs a 2.00° slope at a constant 10.0 m/s while encountering wind resistance and friction totaling 500 N. Review on applying Newton's second law. Here I don't write the steps explicitly. After so many problems you have solved, I expect you to know the steps. In exams, I don't write the steps. (a) How much engine force F (in Newtons) is needed to keep the car at constant speed up on the incline? DON't use scientific notation. (b) Calculate the engine's power output in hp. (1 hp = 746 W). (There is a second formula to calculate power.)
