in an experiment, the motion data for a toy truck was recorded in the position - time graph. which statement describes the motion of the toy truck? a the truck starts moving at t = 0.8 s and its speed remains constant. b the truck starts moving at t = 0.8 s and its speed increases with time. c the truck starts moving at t = 0.0 s and changes its direction of motion at t = 0.8 s. d the truck starts moving at t = 0.0 s and its speed increases with time after t = 0.8 s.

in an experiment, the motion data for a toy truck was recorded in the position - time graph. which statement describes the motion of the toy truck? a the truck starts moving at t = 0.8 s and its speed remains constant. b the truck starts moving at t = 0.8 s and its speed increases with time. c the truck starts moving at t = 0.0 s and changes its direction of motion at t = 0.8 s. d the truck starts moving at t = 0.0 s and its speed increases with time after t = 0.8 s.

Answer

Brief Explanations:

In a position - time graph, the slope represents speed. The toy - truck has a zero slope (no motion) from (t = 0) s to (t=0.8) s. After (t = 0.8) s, the graph is a straight line, indicating a constant non - zero slope which means constant speed.

Answer:

A. The truck starts moving at (t = 0.8) s and its speed remains constant.
