The time of motion of ball A before they collide is 5.1 seconds.
<h3>
Time of motion</h3>
The two balls will collide at a time "t" when they attain a certain height "h".
<h3>The equation of motion</h3>
The equation of motion of the two balls is given as follows;
<em />
<em>when they collide;</em>
- A would have traveled, (t + 4) seconds
- B would have traveled t seconds
Thus, the time of motion of ball A before they collide is (1.1 + 4) = 5.1 seconds.

Answer:1.6 kJ
Explanation:
Given
mass of truck
speed of truck
We know kinetic Energy is the energy possessed by a moving body such that its value is given by product of mass and square of speed.
Answer: It would destroy the Earth's surface.
I remember reading this questions in What If? by Randall Munroe. Great book, I suggest you check it out. Anyway, the answer. The Earth is revolving as well as spinning on its axis at the same time. This basically means that thee atmosphere is also spinning at the same speed. But due to the frame of reference, we don't notice anything. If the Earth suddenly stops spinning, then the atmosphere, going according to the first law of motion will still be spinning at the same speed. This would produce supersonic winds at such a scale that it will be compared to an atomic explosion. Anything not in a nuclear bunker will probably be ripped apart by the force of the wind.

<h2>Archimedes' principle</h2>
''states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces.''
Archimedes principle equation is given as
buoyant force = density of fluid x volume of displaced fluid x acceleration due to gravity. or
<em>Fb=-density*gravity*volume </em>
<em>For example,</em> a ship that is launched sinks into the ocean until the weight of the water it displaces is just equal to its own weight.
