Acar starts from rest and increases its speed to 18 m/s in 22 seconds. what is the cars acceleration

Magnitude of acceleration = (change of speed) / (time for the change)

Change of speed = (speed at the end) - (speed at the start)

Change of speed = (18 m/s) - (0 m/s) = 18 m/s

Time for the change = 22 sec

Magnitude of acceleration = (18 m/s) / (22 sec)

Magnitude of acceleration = 0.818 m/s²

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.
