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:

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 seconds10mph = 4.47m/s5mph = 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

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
