Question

Have your partner simply drop a centimeter ruler between your fingers. Catch it and note the number of centimeters the ruler fell during your reaction time. 2. Distance pased ()- 30023 m The distance d the ruler fell is related to its time of fall (your reaction time) t and the acceleration g due to the gravitational force acting on the ruler according to Solving for the time of fall and simplifying yields 2d 12 Using g 9.8 m/s we have t 0.45V/d s, where d is in meters. Calculate your reaction time using the formula above. Reaction time (t)-

    1. [25 points) Idealized frictionless free fall of an object that is dropped from being at rest at i = 0. For the following question, to model the free fall of a falling rock, assume the usual idealizing simplifications for solving "free fall" problems. Consider the following experiment. A rock with a mass of m= 2 kg is dropped at the time t = 0 from a height of 140 m above ground. Assume that the rock is simply dropped...
