Question

the lift is going up the total mass of the lift and the passenger is 1000kg. The variation in the speed of the lift is given as the graph the tension in the rope pulling the lift at t= 10.5 sec will be​

Answer 1

Answer:

35 is the correct answer

Answer 2

Explanation:

At 10.5th second lift is moving upward with acceleration

a= 0.36/2

=−1.8m/s

Tension in rope − T= m(g−a) = 1500(9.8−1.8)

= 12000N

Hope it helps ☺☺
