At eccentricity = 0 we get a circle For 0 < eccentricity < 1 we get an ellipse for eccentricity = 1 we get a parabola for eccentricity > 1 we get a hyperbola for infinite eccentricity we get a lineSHOW FULL ANSWER
Answer:
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
For part a we can use the kinematic formula distance= velocity(initial)*time+1/2*acceleration*time^2
we know there is only velocity in the horizontal and none in the vertical so v initial in this case is 0, acceleration is gravity =9.81m/s^2
plug in .95=(1/2)*9.81*t^2 solve for t
t=.44seconds
Now for part b we know there is no horizontal acceleration so distance= velcoity* time
we will use horrizontial velocity and the time we just found
distance= .8m/s*.44seconds
=.35 meters
Energy transfer is when a energy transfers from a body/object to another.
Energy transformation is when energy is transformed into another form.
There is an energy transfer from the heat lamp to the baby zebra.
Explanation:
Power = work / time
Work = force × distance
Therefore:
Power = force × distance / time
Since the distance is the same, he would have to either increase the force he exerts or decrease the time (increase his velocity) in order to increase the amount of work done.
