A man walking at 0.5 m/s increases his pace to 0.8 m/s in 3 seconds. What is his acceleration?

Respuesta :

AL2006

Acceleration = (change in speed) / (time for the change)

Change in speed = (New speed) - (old speed)

Change in speed = (0.8 m/s - 0.5 m/s) = 0.3 m/s

Time for the change = 3 seconds

Acceleration = (0.3 m/s) / (3 s)

Acceleration = 0.1 m/s²
