Which object will have more kinetic energy a x a stationary bulldozer b x a car driving at a speed of 2 m/s c x a bird flying at a speed of 2 m/s d x they all would have the same kinetic energy

... Kinetic energy is energy of motion, so the bulldozer doesn't have any.

... Kinetic energy is proportional to mass and speed². 
The bird and the car both have the same speed, so their kinetic energy
just depends on their mass.  The car has more mass than the bird has,
so the car also has more kinetic energy than the bird has. 

Ithink it’s 98 because jajajjajansmsmjs
