I PRELIMINARY QUESTIONS 1. One of the timing devices Galileo used was his pulse. Drop a rubber ball from a height of about 2 m and try to determine how many pulse beats elapsed before it hits the ground. What was the timing problem that Galileo encountered? 2. Now measure the time it takes for the rubber ball to fall 2 m, using a watch or clock with a second hand or seconds display. Did the results improve substantially? 3. Roll the hard ball down an incline that makes an angle of about 10° with the horizontal. First use your pulse and then your watch or clock to measure the time of descent. 4. Do you think that during Galileo's day it was possible to get useful data for any of these experiments? Why?

main step only ( brieflv) Short explanation needed 4 A lift travels up and down between the ground floor (G) and the roof garden (R) of a hotel. It starts from rest, takes 5s to increase its speed uniformly to 2ms, maintains this speed for 5s and then slows down uniformly to rest in another 5s. In the following questions use upwards as positive. 1 [i] Sketch a velocity-time graph for the journey from G to R. On one occasion the lift stops for 5 s at R before returning to G. [ii] Sketch a velocity-time graph for this journey from G to R and back. [iii] Calculate the acceleration for each 5 s interval. Take care with the signs.

I'm stuck on these two questions from the same example Part C If the captain of ship A fires a missile, counts 10.0 ss on his watch, and then fires a second missile, how much time Δt will the captain of ship B measure to have passed between the firing of the two missiles? Part D The captain of ship B knows that ship A uses 2-m-long missiles. She measures the length of the first missile, once it has finished accelerating, and finds it to be only 0.872 mm long. What is the speed u of the missile, relative to ship B? Use c=3×108m/s=3×108m/s.
