A lift of mass 400 kg is hung by a wire. Calculate the tension in the wire when the lift is

A lift starts from rest with a constant upward acceleration It moves 1.5 m in the first 0.4 A person standing in the lift holds a packet of 2 kg by a string Calculate the tension in the string during the motion .

A lift is going up. The total mass of the lift and the passengers is 2000kg . The variation of speed of the lift is as shown in the diagram (a) What will be the tension in the rope pulling the lift at time equal to (i) 1s (ii) 6s (iii) 12s ? (b) What will be the average velocity and average acceleration during motion?

One feels heavier in a lift when the lift

A lift is going up. The total mass of the lift and the passengers is 1500kg. The variation in the speed of the lift is given by the graph. (a) What will be the tension in the rope pulling the lift at time t equal to (i) 1a, (ii) 6s, (iii)11s ? (b) What will be the average velocity and the average acceleration during the course of the entire motion?

A lift of mass 1000 kg is going up. The variation in the speed of lift is shown in figure. Then the minimum tension in the rope will be (g=10 m//s^(2))

A body of mass 2 kg is hung on a spring balance mounted vertically in a lift. If the lift descends with an acceleration equal to the acceleration due to gravity ‘ g ’, the reading on the spring balance will be

A man, of mass 60kg, is riding in a lift. The weights of the man, when the lift is acceleration upwards and downwards at 2ms^(-2) are respectively. (Taking g=10ms^(-2) )

A lift is going up. The total mass of the lift and the passengers is 1500 kg . The variation in the speed of the lift is given by the graph shown in Fig . What will be the tension in the rope pulling the lift at (i) t = 1 s , (ii) t =6 s (iii) t = 11 s ? What is the height to which the lift takes the passengers ? During the course of entirs motion What is the average velocity and average acceleration of the lift ? Taken g = 9.8 m//s^(2) .

A body of mass 30kg is hung by a spring balance in a lift. What would be the reading of the balance when the lift is (i) descending with a constant velocity of 5m//s (ii) ascending with a constant velocity of 10m//s .
