How Do Mass and Force Affect Acceleration in a Frictionless System?

[jen@skywi.com]

Homework Statement

A 2kg block hanging off the edge of a table pulls a 3kg block on a frictionless table. What is the mass of the system, the net force on the system, and th acceleration of the blocks.

Homework Equations

F=ma

The Attempt at a Solution

Not sure
20N and 30N so maybe net force 10N but not sure about the rest

Hi there,

To simplify your solution, just look at what is acting on the 3kg block on the frictionless table.

Cheers

I would approach this problem by first identifying the key variables and equations needed to solve it. The key variables in this scenario are the masses of the blocks (2kg and 3kg), the force acting on the system (due to the hanging block), and the acceleration of the system. The equation needed to solve this problem is Newton's Second Law, F=ma.

To find the mass of the system, we simply add the masses of the two blocks together, giving us a total mass of 5kg.

To find the net force on the system, we need to consider the forces acting on the system. The only force acting on the system is the force due to the hanging block, which is equal to the weight of the hanging block (2kg) multiplied by the acceleration due to gravity (9.8m/s^2). This gives us a net force of 19.6N on the system.

To find the acceleration of the system, we can rearrange the equation F=ma to solve for acceleration. This gives us a= F/m. Plugging in the values we know, we get an acceleration of 3.92m/s^2.

In conclusion, the mass of the system is 5kg, the net force on the system is 19.6N, and the acceleration of the system is 3.92m/s^2.
