A block of mass 5 pounds is placed at the end of a spring, of elastic constant 900 N/m, compressed 1 foot. When the spring is released, the block moves along a horizontal plane and after traveling a distance of 40 inches, it rises along a plane inclined at 30° with the horizontal. There is only friction in the 40-inch section traveled horizontally, the coefficient of friction is 0.1. a. Calculate the distance traveled by the block on the inclined plane if the coefficient of friction between the body and the horizontal plane is 0.1 (there is no friction on the inclined section, nor in the 20 cm). b. State when the kinetic energy will be maximum. end fin start inicio %= 0 ------> wwwww 21 30° V = 0

Transcribed Image Text:A block of mass 5 pounds is placed at the end of a spring, of elastic constant 900 N/m,
compressed 1 foot. When the spring is released, the block moves along a horizontal plane
and after traveling a distance of 40 inches, it rises along a plane inclined at 30º with the
horizontal. There is only friction in the 40-inch section traveled horizontally, the coefficient
of friction is 0.1.
a. Calculate the distance traveled by the block on the inclined plane if the coefficient of
friction between the body and the horizontal plane is 0.1 (there is no friction on the inclined
section, nor in the 20 cm).
