A die is tossed into a high arching trajectory from one end of a table to another. Which statement is correct regarding the die at the peak of its trajectory? a. The height of the peak is independent of the initial velocity.
b. The vertical component of the velocity is zero at the peak
c. The time to get to the peak is independent of the initial velocity
d. The acceleration of the die at the peak is downward, with magnitude g.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

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
