Question

Please help me! I don't get it!
What is the mass of a sack of sand weighing 520 N? Giving 500 N of force at what rate will accelerate? Thanks!!

Answer 1

1) The mass of the sack can be found using the following equation:
W=mg
where
- 'W' is the weight force acting on the sack (520 N)
- 'm' is the mass
- 'g' is the acceleration due gravity (9.8 m/s^2)

Substituting for m (mass) gives us m=W/g . Using this equation, you should be able to work out the mass.

2) For this part, I am assuming the 500 N force is acting in a horizontal direction.
The equation we need to use is F=ma (Newton's second law)
- 'F' is the force applied on the sack (500 N)
- 'm' is the mass of the object (found in the previous answer)
- 'a' is the acceleration of the object

Rearranging the equation gives us a=F/m which we can use to find the acceleration.

PS: This is my first answer on this site. If anyone finds any errors, please let me know. I am happy to change them.
