If a bicycle that is traveling at 5 mph speeds up to 10 mph in 5 seconds, what is the bicycle’s acceleration?

If a bicycle that is traveling at 5 mph speeds up to 10 mph in 5 seconds, the bicycle's acceleration will be 0.45m/s²

HOW TO CALCULATE ACCELERATION:

a = (v - u) ÷ t

Where;

a = acceleration

v = final velocity (m/s)

u = initial velocity (m/s)

t = time (s)

a = (4.47 - 2.24) ÷ 5

a = 2.23 ÷ 5

a = 0.45m/s²
