Question

What is the magnitude of the acceleration of a 25 kg bike if it is being pedaled in a southerly direction with a constant unbalanced force of 5 N? A. 0.2 m/s² B. 5 m/s² C. 20 m/s² D. 125 m/s²

Answer 1

Answer;

= 0.2 m/s²

Step-by-step explanation;

From second Newton's law of motion;

F = ma , where F is the resultant force, m is the mass and a acceleration

In this case;

M = 25 kg, F = 5 newtons

Therefore;

a = F/m

= 5 /25

= 0.2 m/s²
