A man of mass 50 kg is standing in an elevator. if elevator is moving ...
Explanation:
When the elevator is moving upwards with an acceleration of g/3, the apparent weight of the man in the elevator is given by the equation:
Apparent weight = Actual weight + (ma)
where m is the mass of the man, a is the acceleration of the elevator and g is the acceleration due to gravity.
Therefore, the apparent weight of the man in the elevator is given by:
Apparent weight = m(g + a)
Substituting the values of m, g and a in the above equation, we get:
Apparent weight = 50(10 + 10/3)
= 50(40/3)
= 2000/3 N
Calculation of work done:
When the elevator moves a distance of 12 m, the work done by the normal reaction of the floor of the elevator on the man can be calculated as follows:
Work done = Force x Distance
The force acting on the man is equal to the apparent weight of the man, which is 2000/3 N. The distance moved by the man is 12 m. Therefore, the work done by the normal reaction of the floor of the elevator on the man is given by:
Work done = Force x Distance
= (2000/3) x 12
= 8000 J
Therefore, the work done by the normal reaction of the floor of the elevator on the man when the elevator moves by a distance of 12 m is 8000 J.
When the elevator is moving upwards with an acceleration of g/3, the apparent weight of the man in the elevator is given by the equation:
Apparent weight = Actual weight + (ma)
where m is the mass of the man, a is the acceleration of the elevator and g is the acceleration due to gravity.
Therefore, the apparent weight of the man in the elevator is given by:
Apparent weight = m(g + a)
Substituting the values of m, g and a in the above equation, we get:
Apparent weight = 50(10 + 10/3)
= 50(40/3)
= 2000/3 N
Calculation of work done:
When the elevator moves a distance of 12 m, the work done by the normal reaction of the floor of the elevator on the man can be calculated as follows:
Work done = Force x Distance
The force acting on the man is equal to the apparent weight of the man, which is 2000/3 N. The distance moved by the man is 12 m. Therefore, the work done by the normal reaction of the floor of the elevator on the man is given by:
Work done = Force x Distance
= (2000/3) x 12

Therefore, the work done by the normal reaction of the floor of the elevator on the man when the elevator moves by a distance of 12 m is 8000 J.
