Question

if the box is moving towards the right, how will its mot change? 25 n 15 n it will speed up it will immediately stop it will maintain constant speed it will slow down

Explanation:

Step1: Calculate net force

The force on the left is \(25N\) (opposite to the direction of motion) and the force on the right is \(15N\) (in the direction of motion). Net force \(F_{net}=15 - 25=- 10N\) (negative sign means opposite to the direction of motion).

Step2: Analyze motion

According to Newton's second law \(F = ma\) (where \(F\) is force, \(m\) is mass, \(a\) is acceleration). Since \(F_{net}<0\) (opposite to the direction of motion), the acceleration \(a<0\). When acceleration is opposite to the velocity (box is moving right, acceleration is left), the speed of the box will decrease.

Answer:

It will slow down
