Answer:
option C
Explanation:
The correct answer is option C
When the driver takes the sharp right turn the door will exert rightward pressure on the driver.
When the driver takes the sudden right turn the tendency of the body is to be in the straight line by the vehicle moves in the circular path so, as the vehicle turns it applies a rightward force on you.
The pushing of the door to you because of the centripetal force acting on the car due to sudden sharp turn.
<span>A center-seeking force related to acceleration is centripetal force. The answer is letter A. The rest of the choices do not answer the question above.</span>
Potential energy and kinetic energy
Answer:
1 mile
Explanation:
We can use the following equation of motion to solve for this problem:

where v m/s is the final take-off velocity of the airplane,
initial velocity of the can when it starts from rest, a is the acceleration of the airplanes, which are the same, and
is the distance traveled before takeoff, which is minimum runway length:


From here we can calculate the distance ratio


Since the 2nd airplane has the same acceleration but twice the velocity


So the minimum runway length is 1 mile
