Answer: 0.5m/s²
Step-by-step explanation:
Given that,
acceleration of bike (a) = ?
Mass of bike (m) = 20kg bike
(Note that the displacement of the bike is in the northerly direction)
constant unbalanced force (f) = 10 N
According to Newton's second law of motion, the acceleration of the bike will be directly proportional to force acting on it but inversely proportional to the mass of the bike.
Hence, Force α mass x acceleration
f = ma
Make a the subject formula
a = f / m
Now find the acceleration of the bike
a = 10N / 20kg
a = 0.5m/s²
Thus, the acceleration of the bike pedaled in the northerly direction is 0.5m/s²
