[#211] Marching speed You sing a suitably chosen tune at 84 beats per minute and walk (in time, exactly one step per beat) with a step length of 0.90 metres. What is your speed in km/hr? (Hint: use the multiply by one technique from week 1. It's worthwhile writing this out fully.) Your speed is km/hr. (Hint: how many significant figures?) Enter answer here [#212] Your average speed You walk the first 0.20 km at 1.0 m/s and the next 0.20 km at 2.0 m/s. What is your average speed? (Be careful.) Your average speed is m/s.

A two-legged robot is programmed so that upon switching it on, it will do a repetitive pair of steps; one step towards east and then one step towards north, with each step correspoding to equal lengths. If after making 1000 pairs of steps, the robot can be found at 956.8m, 45° NE, what is the length of each step?
Assume your hair grows at a rate of 1/44th of an inch per day. How fast is that in nm/s (nanometers per second)? Given that a typical atom is on the order of 1 x 10^(-10) m in diameter (see Table 1.3 on page 18 of the textbook), at approximately what rate does the protein synthesis that assembles your hair strands deposit atoms in units of atoms per second? I need the second question to be rounded to 1 significant digit.

In SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably more comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical intuition. More precisely, show that (a) 1.0 m/s = 3.6 km/h and (b) 1.0 m/s = 2.2 mi/h.
