Question

15 kg Box experiences too hard auto forces on a frictionless surface as shown below. What is the objects acceleration? Use a positive negative sign to indicate the direction.

Answer 1

We need to analyze the system

`-35+25=ma`

where m is the mass of the box

m=15kg

`-35+25=15a`

then we can isolate the acceleration

`a=(-35+25)/(15)=-0.67\text{ }(m)/(s^2)`
