Question

If a net horizontal force of 175 N is applied to a bike which causes the bike to accelerate at 4.1 m/s^2, what is the mass of the bike?

A) 42.7 kg
B) 43 kg
C) 41 kg
D) 44 kg

Answer 1

Using Newton's second law, the mass of the bike is calculated by dividing the net horizontal force by the acceleration, resulting in a mass of approximately 43 kg.

Step-by-step explanation:

If a net horizontal force of 175 N is applied to a bike which causes the bike to accelerate at 4.1 m/s2, the mass of the bike can be calculated using Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = m * a).

To find the mass (m), you rearrange the formula to m = F/a. Substituting the given values, m = 175 N / 4.1 m/s2 = 42.68 kg. When rounding to the nearest whole number, the mass of the bike is 43 kg (option B).
