A car is moving in a straight line with the same speed of 100 m/s ,the acceleration in this case is
a= 100 m/s2
a=10 m/s2
a=1000 m/s2
a= 0 m/s2

a = 0m/s²

Explanation:

Average acceleration = (change in velocity)/(time it takes). Since the car's change in velocity is zero, its acceleration is zero.

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.
