Question

larry the rock and the force. someone is applying a force of 419 n to the right on larry the rock. larry the rock has a mass of 60 kg. in order for larry the rock to be at a constant velocity of 2 m/s to the right, what must be the force applied to the box have to be? a. 100 n to the left b. 100 n to the right c. 25 n to the left d. 419 n to the left

Explanation:

Step1: Recall Newton's first - law

An object moving at a constant velocity has zero net force acting on it.

Step2: Analyze horizontal forces

A force of 100 N is applied to the right. To have a net force of zero (constant velocity), an equal and opposite force must be applied.

Answer:

A. 100 N to the left
