Newton's 2nd Law: Determine Force Magnitude (6.05 N, 6.1 m/s, 2.5 kg)

AI Thread Summary
A 2.5 kg mass accelerates at 6.1 m/s² at an angle of 37° north of east, with one force of 6.05 N directed north. To determine the magnitude of the second force, it is essential to apply Newton's second law, F = ma, recognizing that the net force must match the acceleration direction. The discussion emphasizes breaking down the forces into components to solve for the unknown force. There is a correction noted regarding the acceleration units, confirming it should be 6.1 m/s². Understanding the vector nature of forces is crucial for solving this problem accurately.

A 2.5 kg mass accelerates at 6.1 m/s
in adirection 37◦north of east. One of the two
forces acting on the mass has a magnitude of
6.05 N and is directed north.
Determine the magnitude of the second
force.
Answer in units of N
I know you have to break it up into multiple components, but otherwise i don't have a clue of what to do

If a mass accelerates in a certain direction, the net force applied to the mass must act in the same direction.

F = ma is a vector equation.
 


ya, key word here is net force, two forces accelerating at 6.1m/s/s, one of which was given, just get the N and magnitude correct for the other.

if you are the marker for my exam, i think i'll be gone! amended the units for acceleration...hahaha

Just pointing out the acceleration is 6.1 m/s2. It was beginning to bug me now that I've seen it in multiple threads :-)
 
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...
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...
