    How can I accurately calculate the duration of a free fall jump?

    Thank you. I was half-way there, just forgot to double the time.

    How can I accurately calculate the duration of a free fall jump?

    I attempted calculations using the total displacement as 0, and again as position = 2.7m, but I'm missing something because I just can't get the answer. This seems like it should be much simpler. I'm assuming the initial velocity is zero, but is that an incorrect assumption? Should I be trying...

    How can I accurately calculate the duration of a free fall jump?

    A. Here is the stated inquiry: A man jumps to a vertical height of 2.7 m. How long was he in the air before returning to Earth? B. Equations used: Y = Yo + VoT + (1/2)gT2 (Y because motion is in the vertical direction) C. Attempted solution: Because the total...

    Calculating Time and Velocity in One-Dimensional Kinematics

    Thank you all! I set the distance equations equal to each other, eliminating X as a variable essentially and solving for t. I checked my answers with those provided in the back of the book and they were correct.

    Calculating Time and Velocity in One-Dimensional Kinematics

    I am reviewing General Physics for the MCAT and have a question regarding kinematics in one dimension. The question reads as follows: A speeding motorist traveling 120 km/h passes a stationary police officer. The officer immediately begins pursuit at a constant acceleration of 10.0 km/h/s...
