Grade 12th passAIPMT
A person of mass 8 kg enters a lift and selects the floor he wants . The lift now accelerates at 1 m/sec^2 for 2 sec , then goes with constant vel . As the lift approaches his floor , it decelerates at the same rate it accelerated . If the lift cable can withstand a tension of 2x 10^4 N and the lift itself has maas of 500 kg , how many persons can it safely carry at once .
