Answer:
35 mph
Explanation:
The key of this problem lies in understanding the way that projectile motion works as we are told to neglect the height of the javelin thrower and wind resistance.
When the javelin is thown, its velocity will have two components: a x component and a y component. The only acceleration that will interact with the javelin after it was thown will be the gravety, which has a -y direction. This means that the x component of the velocity will remain constant, and only the y component will be affected, and can be described with the constant acceleration motion properties.
When an object that moves in constant acceleration motion, the time neccesary for it to desaccelerate from a velocity v to 0, will be the same to accelerate the object from 0 to v. And the distance that the object will travel in both desaceleration and acceleration will be exactly the same.
So, when the javelin its thrown, it willgo up until its velocity in the y component reaches 0. Then it will go down, and it will reach reach the ground in the same amount of time it took to go up and, therefore, with the same velocity.
Answer:<em> inversely proportional to </em>
The work relates the displacement and Force
W = F. d Joules
Where W= work,
F = Force ,
d = displacement of object
From the above equation
<em> force and displacement are inversely proportional </em> and work and force are directly proportional
(17.36 micron/30sec) x (1x 10⁻⁶ meter/micron) x (1km/1,000 m) x (3600 sec/hr) =
(17.36 x 10⁻⁶ x 3600) / (30 x 1000) km/hr =
<em>0.000 002 083 km/hr</em>
The law of conservation of energy states that energy is neither created nor destroyed, but can be converted from one form to another.
When the book was at the shelf, its kinetic energy was zero and its potential energy was maximum. As it fell, its potential energy stated converting to kinetic energy. Before the book directly hits the ground, its kinetic energy is maximum and its potential energy is zero.
Based on the above explanation, at the moment the book landed on the floor, ALL the potential energy was converted to kinetic energy, so the kinetic energy = 67 Joules.
