the kinetic energy of an object depends on its mass and its speed.
it does not depend on the object's velocity as long as its speed doesn't change, the object has the same kinetic energy no matter what direction it's moving.
a. the acceleration increases.
answer : distributive justice
explanation : a fair allocation of burdens and benefits in society is know as distributive justice.
according to armstrong distributive justice is the advantage and load of our lives are shared between members of a society.
distribution justice is concerned with the fair allocation of advantage between different members of a society.
so, answers is the b.
two keys are needed to solve this problem. first, the conservation of momentum: allowing you to calculate the cart's speed after the elephant jumped onto it. it holds that:
so, once loaded with an elephant, the cart was moving with a speed of 4.29m/s.
the second key is the kinematic equation for accelerated motion. there is one force acting on the cart, namely friction. the friction acts in the opposite direction to the horizontal direction of the velocity v0, its magnitude and the corresponding deceleration are:
the kinematic equation describing the decelerated motion is:
it takes 11 seconds for the comical elephant-cart system to come to a halt.
