A skydiver is falling at 50 m/s when they open their parachute. The parachute slows them at a rate of 4 m/s^2 until they reach terminal velocity of 3 m/s. How long does it take to reach terminal velocity?

    15.67 seconds

    Explanation:

    Using first equation of Motion

    Final Velocity = Initial Velocity + (Acceleration * Time)

    v = u + at

    v=3

    u=50

    a = - 4 (negative acceleration or deceleration)

    3 = 50 + (-4 * t)

    -47/-4 = t

    Time = 15.67 seconds

    Answer:11.75 seconds

    Explanation:

    Answer:

    Explanation:

    Parameters:

    Final velocity V1 = 3m/s

    Initial Velocity V2 = 50m/s

    Acceleration = 4m/s2

    Time = ?

    V1 = V2 + at

    V1 - V2 = at

    Therefore t = V1 - V2 / a

    t = 3-50 / (-4)

    t = - 47 / (-4)

    t = 11.75sec

    It'll take 11.75 seconds to reach terminal velocity of 3m/s.
