    Acceleration (a)= 5.71m/s^{2}

    Time= 15.46 seconds

    Explanation:

    A.) Time

    1.) Through derivation, we will be able to determine that the formula for time is:

    t=\frac{d}{v}

    2.) Substitute the values:

    \frac{1365m}{88.3m/s}

    3.) Through basic algebra, we will get this

    \frac{1365m}{88.3m/s} = 15.46 s

    B.) Acceleration

    1.) The basic formula for acceleration is:

    a=\frac{Final velocity- initial velocity}{time}

    2.) Subsitute the values

    \frac{88.3m/s-0m/s}{15.46}

    *Notes:

    1.) Your question stated no initial velocity, only the final velocity

    2.) The value we inputted for time is the one that we solved for in section A

    3.) Solve for the answer

    a=\frac{88.3m/s}{15.46} = 5.71 m/s{2}

    Explanation:

    In some of the isolated places in the Philippines, relief goods are delivered using helicopter. A helicopter moving horizontally with a constant velocity of 120 m/s at an altitude of 1200 m. The plane releases a “care package” that falls to the ground along a curved trajectory. Ignoring air resistance, (a) determine the time required for the package to hit the ground. Suppose that the plane is travelling with twice the horizontal velocity (240 m/s), (b) determine the time required for the package to hit the ground

    Question :

    A plane has a takeoff speed of 88.3 m/s and requires 1365 m to reach that speed. Determine the acceleration of the plane and the time required to reach this speed.​



    answer :

    vi = 0 m/s

    vf = 88.3 m/s

    d = 1365 m

    answer to be found :

    vf² = vi² + 2*a*d

    (88.3 m/s)² = (0 m/s)² + 2*(a)*(1365 m)

    7797 m²/s² = (0 m²/s²) + (2730 m)*a

    7797 m²/s² = (2730 m)*a

    (7797 m²/s²)/(2730 m) = a

    a = 2.86 m/s²

    vf = vi + axt

    88.3 m/s = 0 m/s + (2.86 m/s²)*t

    (88.3 m/s)/(2.86 m/s²) = t

    t = 30. 8 s

    Distance = 1365m

    Initial velocity = 0(starts from rest)

    Final velocity = 88.3m/s

    V sqr = u sqr +2as

    88.3 sqr = 0 + 2 (1365)a

    7796.8 = 2739.a

    a = 7796.8/2739

    a=2.856m/sec sqr

    V= u+at

    88.3 = 0+2.856.t

    t=2.856/88.3

    t=30.917 seconds

    Hope u understand
