Answer:
26.8 seconds
Explanation:
To solve this problem we have to use 2 kinematics equations: *I can't use subscripts for some reason on here so I am going to use these variables:
v = final velocity
z = initial velocity
x = distance
t = time
a = acceleration
First let's find the final velocity the plane will have at the end of the runway using the first equation:
Now we can plug this into the second equation to find t:
Then using 3 significant figures we round to 26.8 seconds
Answer:
Draw the vector triangle (head to tail)
Let 8 be adjacent and 4 the opposite side
tan theta = 4 / 8 = .5
theta = 26.6 deg
No, there isn't. Please consult your doctor if this is the case with yours or someone you know.
Answer:
Hewo My Lovelys!!
Answer is down below!!
Explanation:
The answer is C) The nail exerts an equal force on the hammer in the opposite direction.
Reason: The Newtons third law states that there is an equal an opposite reaction for every action. When hammer pushes the nail, the nail will push the hammer back in opposite direction. When the hammer hits a nail then nail will exert the equal and opposite force to the hammer. These both objects will exert force on each other in opposite directions.
Hope this helps!! =3
Have a great day, evening, of night!! <3
