Question

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

Answer 1

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:

• The acceleration of the bicycle can be calculated by dividing the change in velocity by time. That is;

a = (v - u) ÷ t

Where;

a = acceleration

v = final velocity (m/s)

u = initial velocity (m/s)

t = time (s)

• According to this question, a bicycle that is traveling at 5 mph speeds up to 10 mph in 5 seconds

1. 10mph = 4.47m/s
2. 5mph = 2.24m/s

a = (4.47 - 2.24) ÷ 5

a = 2.23 ÷ 5

a = 0.45m/s²

• Therefore, 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
