Answer :
Tension in the Cable is 0.87 m/s6^2, Elevator's speed after it has moved 10m is 1.6*10^5 N, Work done by gravity is 1.47 * 10^3 N, Elevator Kinetic Energy is 13897.5J and Elevator Speed after rising to 10m is 4.312 m/s.
Tension is a pulling force that operates in one dimension along the cables' axes in the opposite direction from the direction of the applied force. The combined weight of the elevator box and the passenger riding inside it, in the case of an elevator, provides the pulling force in the cables is called Tension.
A moving object or particle's kinetic energy, which depends on both mass and speed, is one of its characteristics. The type of motion can be vibration, translation, rotation around an axis, or any combination of these. Kinetic energy is a type of energy that an item or particle possesses as a result of motion.
We know that,
Tension in the Cable
T = m(g+a) = g+a = T/m = 16 * 103 / 1500 = 10.67 m/s2
a = 10.67 - 9.8 = 0.87 m/s6^2
Elevator's speed after it has moved 10m.
U^2 = u^2 +2as
= 1.22 +2*0.87*10
=1.6*10^5 N
Work done by gravity = mg * 10 = 14700 * 10 = 1.47 * 10^3 N
Elevator Kinetic Energy = 1/2 mv^2 = 1/2*1500*18.53 = 13897.5J
Elevator Speed after rising to 10m ,
U^2 = u^2 +2as = 1.2 +2*0.87*10 = 18.6
U =(18.6)^1/2=4.312 m/s
