Problem P. 4752. (September 2015)
P. 4752. The string of a bow is pulled by a force of 200 N, such that the arrow is moved backwards by a distance of 50 cm. The applied force is proportional to the displacement of the midpoint of the string. With this bow an arrow of mass 40 g is shot vertically upwards. To what maximum height can the arrow fly if 40% of the elastic energy is used?
