big bee has a mass of 5 kg and hits a newly cleaned windshield accelerating at a rate of 2 m/s2.
little bee has a mass of 3 kg and is accelerating at a rate of 4 m/s2.

which hits the windshield with a greater force? (show your work below as proof.)

According Newton's 2nd Law of Motion  the force is directly proportional to the mass and to the acceleration of a body:

   (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 and acceleration , the force is:

  (2)

Then:

>>>Force for Big bee

For Little Bee with a mass and acceleration , the force is:

   (3)

Then:

>>>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.

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?
