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 as shown in Fig.
. What will be the tension in the rope pulling the lift at time `t` equal to `1s` ?

The total mass of an elevator with a 80 kg man in it is 1000 kg. This elevator moving upward with a speed of 8 ms^-1 is brought to rest over a distance of 16 m. Calculate the tension T in the cable supporting the elevator

Three equal weights of mass 2 kg each are hangning os string passing over a fixed pulley as shown in fig.What is the tension in the string connectig weights B and C? .

If a lift can move a load of 5000 kg with a speed of 1ms^-1 , where is the power of the lift?

The fig shows the position the position- time graph of a particle of mass 4 kg. What is the Force on the particle for t 4s, impulse 0 < t < 4 s ?

Two stones are thrown up simultaneously from the edge of a cliff 200 m high with initial speeds of 15 m s^-1 and 30 m s^-1 . Verify that the graph shown in Fig. 3.27 correctly represents the time variation of the relative position of the second stone with respect to the first. Neglect air resistance and assume that the stones do not rebound after hitting the ground. Take g = 10 m s^-2 . Give the equations for the linear and curved parts of the plot.
