A comprehensive punch with majority 45 kg is entity pushed up a cobble at a 32o tpurpose at a invariable swiftness by a fiction interfering analogous to the tpurpose control 7.80 m. If the coefficient of kinetic abrasion is 0.25, what is:
The intensity the fiction is interfering on the punch.
The employment manufactured by the fiction on the punch.
The intensity of abrasion.
The employment manufactured by the abrasion intensity.
A start with negligible majority is drooping present to a executive such that the purpose of the start at equilibrium is at the 0 cm token on the executive. If a 3.0 kg majority is drooping from the start and it stretches so that the purpose of the start is at the 17 cm token, what is the start invariable k?
