Force & Mass: Calculating Acceleration

AI Thread Summary
When a net force is applied to an object, the acceleration is determined by the formula F = m * a. If the mass is increased by a factor of 7 while keeping the force constant, the acceleration will decrease. Specifically, the new acceleration can be calculated by rearranging the formula to a' = F/m'. Thus, if the original acceleration is 9.70 m/s², the new acceleration will be 1.39 m/s². Understanding the relationship between force, mass, and acceleration is crucial for solving such problems.

Homework Statement



Suppose that a net force F gives an object with a mass of m an acceleration of 9.70 m/s/s.

Suppose that the mass were increased by a factor of 7.0. The new acceleration would be ___ m/s/s

Homework Equations



fnet=Mass*acceleration

The Attempt at a Solution



well i know that fnet=MA is the formula to use but don't know how to interperet it if a factor changes

thanks :)

Mass does not effect acceleration.

Hint: its a very simple problem.

This is not true at all.

If the force is constant, and your new m' = 7m, what must a' = so that the force remains hte same?
 

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'

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...
