Answer:
Explanation:
Formula of acceleration a = fm
A = 68 x 386
= 26248
I think the answer would be true that’s my opinion
Mechanical advantage is defined as

MA = 4
now we will have

as we need to pull up a box of weight 200 N
now by above formula we can find how much force it requires to pull up the box



so it requires 50 N force to pull the weight of 200 N
1 w = 1N/s the change in total energy =mgh = 600*4 = 2400N. 2400N/200N/s = 12seconds
