Question

What is Newton's Second Law? a. If a force is exerted on an object, then that object will experience an acceleration throughout the duration of that force An object in motion will stay in motion and an object at rest will stay at rest if no external forces are exerted on the object. O c. All objects are attracted to each other due to the force of gravity. d. For a system of interacting objects, the force that object 1 exerts on object 2 is equal and opposite to that of object 2 on object 1. QUESTION 2 During the lab, when looking at both the Force v. Time and Acceleration v. Time plots, how did the position of the peak acceleration compare to the peak position of the force? a. The peak acceleration always came before the peak force. The peaks occur at the same time. OC. The peak force always came before the peak acceleration. d. There is no relationship between the position of the peaks.

Explanation / Answer

1.

As per 2nd law of motion

F= ma

So option (a) is correct

=======

2. As force is directly proportional to acceleration of the object. So both the events happen simultaneously.

Option ( b) is correct.

======

3.

m= F/a= 3/7= 0.429 m/s^2

=======

4.

Due to friction its speed keep on decreasing till it reached its state of rest.

Option (d) is correct.

======

Comment in case any doubt. Good luck
