Answer:
The correct answer option is energy but not matter.
Answer:
After 1.938 sec velocity of rock will be 36 m/sec
Explanation:
We have given initial velocity at which rock is thrown u = 55 m/sec
Final velocity v = 36 m/sec
Acceleration due to gravity 
According to first equation of motion we know that
, here v is final velocity, u is initial velocity, g is acceleration due to gravity and t is time
So
( Negative sign is due to rock is thrown upward )
So 
t = 1.938 sec
So after 1.938 sec velocity of rock will be 36 m/sec
Answer:
The time interval is 
Explanation:
From the question we are told that
The constant acceleration is 
The displacement is
According to the second equation of motion we have that
given that the blade started from rest
which is the initial angular velocity is 0
So
=> 
substituting values
=> 
=> 
Answer:
east
Explanation:
15km east
_______________
X________
8km west
so you are where the xX is so you are still in the eastward direction
