A man of mass 50 kg is in a lift at ground floor. The man is now on a weight machine. For first 10 s, reading of weighing machine is 60 kg-wt. For next 10 s, it reads 50 kg-wt and for rest of the journey till top floor, reading of weighing machine is 30 kg-wt. Assume that initial and final velocity of lift is zero. Total distance travelled by the lift is 50x m. The value of x is _______.(g=10 m/s2) |
