The acceleration due to gravity on some planet is 18.9 m/s2. if you weigh 1081 n on earth, how much would you weigh on that planet? v

The acceleration is and force is .

Newtons second law of motion that when an object is accelerating its force (weight in current context) can be calculated using his mass:

If we express mass:

We first need to find mass since mass won't change no matter the acceleration.

If we know that acceleration on earth equals then we can calculate our mass:

Then we use this mass and calculate our weight on a different planet:

Hope this helps.

Edit one:

Also note that I have rounded to if wish to get more precise results use .

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
