Question

forces and motion. motion the 50 kg box and another 50 kg box. slow it down. get the two boxes to move at the maximum velocity/speed (40 m/s). is the robot pushing anymore? 1 point yes no is the speed increasing anymore? 1 point yes no press pause. if the boxes are moving to the right what way would you have to start pushing to make it stop/slow down? 1 point left right

Explanation:

Step1: Understand Newton's first - law

An object in motion will stay in motion with a constant velocity unless acted upon by an external force. When the boxes are moving at a constant maximum velocity (40 m/s), there is no net force acting on them in the direction of motion. So the robot is not pushing anymore.

Step2: Analyze speed change

Since the velocity is constant at the maximum speed, the speed is not increasing anymore.

Step3: Apply force for deceleration

To slow down or stop an object moving to the right, a force in the opposite direction (left) must be applied according to Newton's second - law ($F = ma$).

Answer:

1. B. No
2. B. No
3. A. Left
