You watch students doing practice runs on a lacrosse field. You measure the time it takes for a particular student run across the field to be 13.4 ±0.1 seconds. If the length of a lacrosse field is 100.58 ±0.06 m, what is the average velocity of this student? Use error prorogation to find the uncertainty in the result.

You are measuring the average speed of your well-trained dog. The dog runs to the end of a field and back to you. You measure the length of the field, L, and the round-trip time, t, with their uncertainties ΔL and Δt, to calculate the average speed of the dog: v = 2L/t. Using the multiplication and division rule for propagation of uncertainties, select the expression for the absolute uncertainty in the average speed. Form: r= xy or r= x/y...

2. Running up the stairs (5 pts). Time how long it takes for you (or a friend) to run as fast as possible up a staircase. Measure the height of one step and count the steps to find how high you climbed. a) How much mechanical energy did you produce to climb the stairs? b) What was the average mechanical power produced during your climb? c) Estimate the muscle mass in your upper legs (quadriceps, hamstrings, and buttocks). (Recall that...

Required (hand in) 1. By using a 2-meter stick (like the one in lab) marked in millimeters and a stopwatch that measures to 1/100h of a second, you decide to measure the speed of a motorized toy car that travels at a constant velocity. You measure out a 162.0cm interval with the 2-meter stick and time how long it takes the car to travel that distance using the stopwatch. Repeating the experiment 5 times you get the following time data:...
