1. A 10-kg light fixture hangs from the ceiling of an elevator. Two 1-m wires are attached to the ceiling at angles of 45 degree and are attached to the light fixture as shown in the figure below. The elevator moves upward at 2 m/s 2 and downward at 3 m/s 2. Determine the minimum and maximum tension in the wires as the elevator moves 2. A box of mass M sits on a ramp that is at an angle of ? with respect to the ground. A person is pushing the box up the ramp with a force of Fp parallel to the ramp that moves the box up the ramp . The coefficients of static friction and kinetic friction between the box and the ramp are ?s and ?k . Determine how far the box moves up the ramp after a time of ?Explanation / Answer
no figure plss provide it
2) doing 2nd one accept this
Fp - Uk*m*gcostheta = 0 since no a
soo it will move until Fp > Usmgcostheta
