How to Find the Velocity Components After 10 Seconds?

AI Thread Summary
To find the velocity components after 10 seconds, first determine the direction of the acceleration vector using the net force from the three given forces. Calculate the mass of the object using Newton's second law, F = ma, and then apply the formula V = at to find the speed after 10 seconds. The direction of the velocity will match the direction of the acceleration, which can be derived from the angle of the acceleration vector. Finally, resolve the velocity into its x and y components based on the acceleration direction and the time interval. Understanding these relationships will allow for the calculation of the velocity components.

Three forces acting on an objetc are given by F1=(-2.00i + 2.00j)N, F2=(5.00i - 3.00j)N, F3=(-45.0i)N The object experiences an acceleration of magnitude 3.75 m/s2.
a) What is the direction of the accceleration?
b) What is the mass of the object?
c) If the object is initially at rest, what is its speed after 10.0s?
d) What are the velocity components of the object after 10.0s?


The only I'm unable to do is d).
Can someone give me some hints to do it please?

Velocity and Acceleration are vectors; time is a scalar unit. If, for constant acceleration, V = at, what's the direction of the velocity?
 
I don't see how it will help me find the velocity in y and x.
 

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...

Thread 'A cylinder connected to a hanging mass'

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...
