Initial Velocity and Inclined Plane

AI Thread Summary
A block is pushed up an inclined plane with an initial velocity, and the problem seeks to determine when the block's speed will equal its initial velocity again. The final velocity is the initial velocity but in the opposite direction, leading to the equation Initial Velocity + Final Velocity = 0. The discussion highlights the challenge of finding time without specific variables provided. Participants suggest that the angle of the incline and the force equation F=ma are relevant but still express uncertainty about solving the problem without numerical values. The conversation emphasizes the need for additional information to reach a solution.

Homework Statement



A block is given a push up an inclined plane with an initial velocity. At what time will the speed of the block be equal to the initial velocity again? No varialbes are given.

Homework Equations



v= v(initial) + at

The Attempt at a Solution



The final velocity is equal to the initial velocity, but opposite in direction. So, Initial Velocity + Final Velocity = 0. But, I don't know how to find time, because we aren't given any variables to work with.

Looks like you have v, a, and t.

The angle that the incline makes with the horizontal should be involved.
 
So I use the force equation, F=ma, but I still don't know how to solve without any numbers?
 

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...
