Two forces act on a 24-kg object. One force has magnitude 65 N directed 59° clockwise from the positive x-axis, and the other has a magnitude 35 N at 32° clockwise from the positive y-axis. What is the magnitude of this object's acceleration?
A 13.9-kg object hangs in equilibrium at the end of a rope (taken as massless) while a wind pushes the object with a 66.5-N horizontal force. determine the rope\'s angle from the vertical
how long does it take for a person to radiate. Calculate the time of flight.
An electron moving parallel to the x axis has an initial speed of 3.70x10^6 m/s at the origin. Calculate the potential difference between the origin and that point.
A worker pushed a 27 kg block9.2m along a level floor at constant speed with a force directed27°below the horizontal. If the coefficient of kinetic friction is 0.20, how much work was done by the worker's force?
