Answer:
Mass = 30kg
Acceleration = 0m/s/s
Explanation:
The weight of an object is its mass multiplied by the gravitational field strength. On Earth the value often used for gravity is 10N/kg. This means there is 10N of force per kg of mass, so the weight of an object will be 10x its mass. Here we are given a weight of 300N, so to find its mass we simply need to divide it by 10. 300/10 = 30kg. The mass of the box is 30kg.
Because the box is being slid across the floor at a constant speed, the velocity is not changing, therefore the acceleration is 0.
Hope this helped!
