AI Thread Summary
To calculate the tension in the string supporting a 1.89 kg mass accelerating upwards at 3.30 m/s², one must apply Newton's second law (F=ma). The net force (Fnet) acting on the mass is the difference between the tension in the string and the gravitational force. A free body diagram is recommended to visualize the forces acting in the vertical direction. The correct calculation involves summing the forces and accounting for both the weight of the mass and the upward acceleration. Ultimately, the tension in the string can be determined by rearranging the equation to solve for tension.

Homework Statement



A 1.89 kg mass is suspended from a string which is pulled upward. The mass accelerates upwards with an acceleration of 3.30 m/s2. What is the tension in the string?

The way it works here is;

We can't help you until you show your attempt, even if it is totally wrong.

Thanks

Ok I tried 6.237=Fnet
18.53-6.237 =
12.293+6.237=
18.53N But that's whrong
 
From Newton's Law

F=ma

where

F is the force (N)

m is the mass (kg)

a is the acceleration due to gravity. On Earth it is 9.81 N/s^2

Set up a free body diagram and sum for forces in the y direction.

Thanks

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
