According Newton's 2nd Law of Motion the force [tex]F[/tex] is directly proportional to the mass [tex]m[/tex] and to the acceleration [tex]a[/tex] of a body:
[tex]F=m.a[/tex] (1)
We already know the mass and the accelaration of both bees. So, we have to find the force which with each bee hits the windshield. As follows:
For Big Bee with a mass [tex]m_{B}[/tex] and acceleration [tex]a_{B}[/tex], the force [tex]F_{B}[/tex] is:
[tex]F_{B}=m_{B}.a_{B}[/tex] (2)
[tex]F_{B}=(5kg)(2m/{s}^{2})[/tex]
Then:
[tex]F_{B}=10N[/tex]>>>Force for Big bee
For Little Bee with a mass [tex]m_{L}[/tex] and acceleration [tex]a_{L}[/tex], the force [tex]F_{L}[/tex] is:
[tex]F_{L}=m_{L}.a_{L}[/tex] (3)
[tex]F_{B}=(3kg)(4m/{s}^{2})[/tex]
Then:
[tex]F_{B}=12N[/tex]>>>Force for Little bee
At this point we are able to clearly see that Little Bee hits the windshield with a greater force than Big bee.
