The two 0.2kg sliders A and B move without friction around the horizontal circular slot. The sliders are connected by an inextensible cable AB. The system starts from rest in the position shown in the figure. Determine the angle between the tangential acceleration of B and the cable AB at this instance. P=4N 0.8 m A B 45° 0 En
A 60kg woman holds a 9kg package as she stands within an elevator that briefly accelerates upward at a rate of 1/4 of the acceleration due to gravity. The elevator starts from rest. Determine the power supplied by the elevator on the woman carrying a package at t= 3 seconds. 4.98kW O 6.22kW O 3.74kW O 7.46kW
