Solution: Yet again the initial velocity is zero. Determine the liftoff speed and the time. Find the unknowns given initial velocity, acceleration, and distanceĮxample problem: An airplane accelerates down a runway at n m/s² until it finally lifts off the ground after traveling the distance of m meters. Note that here it is easier to find the final velocity first, then plug it into the second equation. The kinematic equations for this case are: 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.
