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

= 0.2 m/s²

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

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
