Question

According to the following position vs. Time graph the bicyclist was

A) moving at a constant speed for the first 2 seconds, then began to speed.

B) not moving for the first 2 seconds, then begin moving and continue to gain speed.

C) slowing down for the first two seconds, then begin moving at a constant speed.

D) not moving for the first two seconds, then begin moving at the constant speed.​

Answer 1

According to the following position vs. Time graph the bicyclist was : D

D. Not moving for the first two seconds, then begin moving at the constant speed.​

Step-by-step explanation:

`Speed = (Distance)/(time)`

Along Y-axis = Distance in meters

Along X-axis = Time taken in second

• For first 2 seconds the The object has not changed its position.There is Zero distance covered.So , Speed = 0
• After 2 second,The Object changed the distance by equal amount in equal interval of time.(Uniform Speed).Hence at each point after 2 second, there is same value speed
