The truck has more KE than the bike
Its true the ionic compounds have a higher melting point
The colder the more likely it is to become a liquid
Answer: 1.22 m
Explanation:
The equation of motion in this situation is:
(1)
Where:
is the final height of the ball
is the initial height of the ball
is the vertical component of the initial velocity (assuming the ball was thrown vertically and there is no horizontal velocity)
is the time at which the ball lands
is the acceleration due gravity
So, with these conditions the equation is rewritten as:
(2)
(3)
Finally:

Think of a wedge as something you put in between objects, so it is a separates objects
