Explanation :
Given equation
This equation is balanced. because the number of reactants is equal to the number of products.
According to conservation of matter and energy,
The conservation of matter and energy states that matter can not create and can not destroy but conserved. we can only change one form to another form of the matter and energy.
So, we can say energy conserved and the ,mass of the system always same over time.
1) The time taken is 3.06 s
2) The distance between the two points is 119.4 m
Explanation:
1)
The motion of the object is a free fall motion, so it is a uniformly accelerated motion with constant acceleration towards the ground. So, we can solve the problem by using the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time taken
In this problem we have
u = 54 m/s is the initial velocity (at point A)
v = 24 m/s is the final velocity (at point B)
is the acceleration (negative since it is downward)
Solving for t,
2)
For this part of the problem, we can use another suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance covered
In this problem we have
u = 54 m/s
v = 24 m/s
Solving for s, we find the distance between point A and point B, which is the distance covered by the object:
