Acceleration = (final velocity - initial velocity) / time
Acceleration = (1.5 m/s - 0.5 m/s) / (5 s - 3 s)
Acceleration = 1 m/s²
Therefore, her acceleration during this time is 1 m/s².
Han’s younger sister is riding her tricycle in a straight line. After 3 s, her speed is 0.5 m/s. After 5 s, her speed is 1.5 m/s. What is her acceleration during this time?
