Experiment 1: Cart A (mass of 500g). Moves to the right at a constant 0.37m/s speed and hits a stationary cart B (mass of 500g). Cart A stops and cart B starts moving at the speed of 0.37m/s to the right.

ill do it for 100, also this isnt 80 its 40

root word, prefixes, and suffixes

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
