The crane pull up the mass with 1150 N. Find the acceleration the mass. m = 100kg
Kren tersebut menarik naik jisim itu dengan 1150 N. Cari daya
paduan pada jisim itu
[use gravitational acceleration, g = 9.81 m s?]​

-1.69 m/s²

Explanation:

We are told the crane pulls up the mass with a force of 1150 N.

This means it is in an opposite direction to gravity and thus acceleration(a) is negative.

Now, the gravity is acting downwards, thus, total force is;

F = mg - ma

1150 = 100(9.81 - a)

Divide both sides by 100 to get;

11.5 = 9.81 - a

a = 9.81 - 11.5

a = -1.69 m/s²

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

i think it would be 5
