Question

q.8. a motorcycle moves from a to d along the path as shown below in 3 seconds. what is the velocity of the motorcycle? a) 1 m/s to the south b) 2 m/s to the south c) 3 m/s to the north d) 5 m/s to the north

Explanation:

Step1: Determine displacement

Displacement is straight - line distance from initial to final point. Here, from A to D, displacement is 3 m south.

Step2: Recall velocity formula

Velocity $v=\frac{\text{displacement}}{\text{time}}$. Time $t = 3$ s and displacement $d=3$ m south.

Step3: Calculate velocity

$v=\frac{3\ m}{3\ s}=1$ m/s south.

Answer:

a) 1 m/s to the South
