A racing cyclist accelerates 5m/s² when she starts from rest. The total mass of the cyclist and her bicycle is 45kg. Calculate the resultant force that produces this acceleration
F=ma
F=45kg*5m/s^2
F=225kg*m/s^2=225N
To calculate the resultant force, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a):
F = m * a
In this case, the mass of the cyclist and her bicycle is given as 45 kg, and the acceleration is given as 5 m/s².
Plugging these values into the equation, we get:
F = 45 kg * 5 m/s²
F = 225 N
Therefore, the resultant force that produces this acceleration is 225 Newtons.
