Question

A box of mass 80kg is raised vertically a uniform acceleration by a force of 1000 newtons on a rope. Calculate the acceleration

Answer 1

Answer:

Explanation:

Assuming g is 10N/kg, its weight is 800N, leaving just 200N to do the actual accelerating.

F=ma → a=F/m → a= 0.25m/s/s

A more formal diagram would have a Force vector arrow of 800N down from body, and another 1000N up and beside it the acceleration vector a going up (typically a double-headed arrow).

If your g is 9.8N/kg (same as 9.8m/s/s) you'll need a calculator, but the method is the same.
