Question

lift is going up the total mass of the left and the passenger is 1000 kg the variation in the speed of the lift is as given in the graph tention in the rope pulling the lift at t is equal to 8 second will be​

Answer 1

Answer:

1. during 0<t<3..lift is accelerating
2. during 3<t<9...lift is moving with constant velocity..
3. during 9<t<12..lift is deccelearting..

in the ques ..the case is of moving with constant velocity...

• T-mg=m(0)
• T=mg
• T=1000(10)
• Tension=10,000N

hope it helps

Good luck ♧♧
