Read the following assertion and reason based question and choose the correct answers:
 
1. Assertion (A) : A student applies the three kinematic equations to analyse the motion of a football moving along a curved path through the air.

Reason (R) : The three kinematic equations are valid only for straight-line motion with constant acceleration.
 
2. Assertion (A): An athlete completes one full lap of a circular track and returns to the starting point. The average velocity for the complete lap is zero.

Reason (R): Average velocity depends on the displacement, not on the total distance travelled.
