To practice Problem-Solving Strategy 11.1 Simple harmonic motion.
The motion of the piston of an automobile engine is approximately simple harmonic. (Figure 1)
A. If the stroke (twice the amplitude) of an engine is 0.100 m and the engine runs at 3500 rpm , compute the acceleration of the piston at the endpoint of its stroke.
B. If the piston has a mass of 0.450 kg , what net force must be exerted on it at this point?
C. What are the speed and kinetic energy of the piston at the midpoint of its stroke?
Part D What are the speed v and kinetic energy K of the piston at the midpoint of its stroke? Express the speed in meters per second and the energy in joules. Separate your answers with a comma.
Part E If the engine runs at 7000 rpm , what are the acceleration, net force, velocity, and kinetic energy? Express acceleration in meters per second squared, force in newtons, speed in meters per second, and energy in joules. Separate yours answers with commas.
Just need parts D and E answered! Will give a thumbs up and leave a positive comment if correct!
