![]() ![]() Solution: In this problem, the initial velocity is zero as well. Determine the liftoff speed and the acceleration. Find the unknowns given initial velocity, time, and distanceĮxample problem: An airplane accelerates down a runway for n seconds until it finally lifts off the ground after traveling the distance of m meters. Here it is easier to find the time first, then plug the time into the second equation. And we use the kinematic equations like so: Solution: As usual we know that the initial velocity is zero. Find the unknowns given initial velocity, final velocity, and distanceĮxample problem: An airplane accelerates down a runway until it finally lifts off the ground having a speed of n m/s after traveling the distance of m meters. So, our kinematic equations will be:Ĭase 4. Solution: The same case with the initial velocity being zero. Determine the time and the distance traveled before takeoff. Find the unknowns given initial velocity, final velocity, and accelerationĮxample problem: An airplane accelerates down a runway at n m/s² until it finally lifts off the ground having a speed of m m/s. To solve the problem, we need to rearrange our kinematic equations like so:Ĭase 3. ![]() Solution: Again we know that the initial velocity is zero. Determine the acceleration and the distance traveled before takeoff. Find the unknowns given initial velocity, final velocity, and timeĮxample problem: An airplane accelerates down a runway for n seconds until it finally lifts off the ground having a speed of m m/s. Thus, we can use our kinematic equations as isĬase 2. The problem assumes that an airplane starts from the rest, hence, its initial velocity is zero. Solution: Although the problem specifies only the acceleration and the time, the third parameter is known implicitly. Determine the final velocity and the distance traveled before takeoff. ![]() Find the unknowns given initial velocity, acceleration, and timeĮxample problem: An airplane accelerates down a runway at n m/s² for m seconds until it finally lifts off the ground. Below are ten types of problems along with the solution formulas. ![]()
