The vertical displacement y(x, t) of a string stretched along the horizontal x-axis is given by y(x, t) = (6.00 mm) cos[(3.25 m-1)x - (7.22 rad/s)t]. (a) what is the minimum time for each complete cycle of the wave? (b) what is the distance between adjacent crests of the wave? (c) how fast does this wave travel?

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

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
