What is the acceleration of a 3kg rock thay is thrown with a force of 18n

Acceleration = 6 m/s²

Explanation:

Given:

Mass of the rock is,

Force acting on the rock is,

From Newton's second law, we know that the net force acting on an object is equal to the product of its mass and the net acceleration. The acceleration of the object acts in the direction of the net force.

Acceleration is the rate of change of velocity.

Here, the mass and net force acting on the rock is given. So, we use Newton's second law to find its acceleration.

Therefore, from Newton's second law, the net force acting on the rock is given as:

Rewriting in terms of 'a', we get

Plug in 18 N for 'F', 3 kg for 'm' and solve for 'a'. This gives,

Therefore, the acceleration of the rock is 6 m/s² in the direction of the applied force.

a is the best answer your welcome

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
