Acar traveling at 30 m/s runs out of gas while traveling up a 10 slope. how far up the hill what coast before starting to roll back down?

264.7 m

Explanation:

The net force felt by the car travelling along the slope is equal to the component of the weight parallel to the slope, so:

where

m is the mass of the car

g = 9.8 m/s^2 is the acceleration of gravity

and the negative sign is due to the fact the force is opposite direction to the motion of the car

The acceleration of the car is therefore:

Now we can find how far the car went up the hill by using the equation:

where

v = 0 is the final velocity of the car

u = 30 m/s is the initial velocity

g = -1.7 m/s^2 is the acceleration

d is the distance covered

Solving for d,

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

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
