I guess so, this is the whole problem I copied word for word from a textbook. Anyway we could use a = F/m to find acceleration, if it is constant

So what equations would we be able to use here?

Yes

Homework Statement What minimum time is required to move a weight of mass 50 kg over a distance of 10 meters along a horizontal floor if the rope used to pull it breaks when the tension exceeds 20kgf, while a force of 10kgf is sufficient to start the weight moving or move it uniformly...

The problem is a lot simpler than what I had made it out to be. The weight of the board, 60 kgf must be balanced by the two supports. Therefore $$ 60 kgf = F_A + F_B$$ We know ##F_B## is 3 times the value of ##F_A##, so $$60 kgf = 4F_A$$, giving us 15 kgf; the other force being triple that...

My bad, I meant to write 60 kgf and not 600 kgf. I've edited the question appropriately

Homework Statement A homogeneous board weighing 60 kgf lies on two supports as shown. Find the forces acting on the supports. Homework Equations $$\frac{F_A}{F_B} = \frac{OB}{OA}$$ where ##F_A## is the force acting on the support on the left, ##F_B## is the force acting on the support on...

I have figured out how to solve the problem. Thanks to those who have helped me. I am answering this thread so other viewers can learn: When the body is hanging by a spring from an unyielding body, such as a ceiling, the spring is elongated by x1. The force acting on the spring equals the...

My bad, I meant to say the weight would become zero.

Homework Statement A weight is suspended from a spring 50 cm long and stretches it by 1 cm. Take the other end of the spring in your hand and rotate the weight in a horizontal plane so that the spring is stretched by 10 cm. What is the velocity of the weight? (The force with which the stretched...
