How much force is needed to get a 2,000kg car to accelerate 5 m/s?

F

=

10

,

000

N

The force necessary would b

Newtons

Explanation:

Using Newton's Second Law that Force is equal to mass times acceleration,  

F

=

m

a

and assuming we are not dealing with friction as we have no coefficient of static friction we can set up ar equation as

F

=

?

m

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
