The initial speed of the meter stick at the moment it was released was

In a reaction time experiment the average displacement of the meter stick is 27 centimeters before it is caught. Calculate the reaction time (in seconds) of the person who caught the meter stick.

Use 9.8 m/s^2 for the acceleration due to gravity, "g".
Express your answer to two decimal places.

    A ball is thrown straight up with an initial velocity of 19.6 m/s. Assume it experiences a constant acceleration of 9.8 m/s^2 down (due to gravity) throughout the entire motion. The motion we will consider is the one from the time it was thrown upward to the time it returns to its initial height, which will take a total of 4 seconds. (a) find an expression for the ball's acceleration as a function of time (b) sketch the acceleration as...
