Question

two children of same weight start climbing a rope where A takes 20sec and B takes 15 sec to accomplish the task what is work done by each​

Answer 1

Answer:A                                  B

m=32 kg                      m=32kg

common height=8 m

t=15 secs                     t=20 secs

therefore,  work done by A n B will be same = FS = maS

                                                 =  32 * 10 *8

                                                  = 2560 J

Power of A =  W/t = 2560/15 = 170.7watt

Power of B            = 2560/20 = 128 watt

hence A has more power comparable to B
