Ajet traveling at 78 m/s accelerates at 23 m/s2 for 6.00 s. what is its final velocity?

216 m/s

Explanation:

The jet is moving with uniform accelerated motion, so we can use the following suvat equation:

where

v is the velocity at time t

u is the initial velocity

a is the acceleration

For the jet in the problem,

u = 78 m/s is the initial velocity

is the acceleration

Substituting t = 6.0 s, we find the final velocity:

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
