FALSE!!! exercise is great for all systems!!
Answer:
For the bird moving in a straight line, the kinetic energy is one-half the product of the mass and the square of the speed: Ek=12mu2.
Answer:
Last option in the list of possible answers, with U235 and n (neutron) in the left (originators) of the reaction diagram.
Explanation:
Uranium 235 (which is a fissile isotope of uranium) plus slow neutrons is what produce the chain reaction that feeds nuclear reactors.
F = mass x acceleration
We have mass = 200kg
and acceleration = 3 m/s^2 so...
F = (200)(3)
F = 600 N
With total velocity 
, the horizontal component of velocity is
Then the horizontal displacement over the first minute is
