Biomechanics IPHY 4540 Problem Set #5 Key 1. If a Giant Galapagos tortoise starts at a velocity of 0 m/s and accelerates at 0.05 m/s 2 for 3 sec (a full out sprint!), what is its velocity at the end of the acceleration? v i = 0 a = 0.05m/s 2 t = 3sec v f = v i + at v f = 0.15m/s 2. How much distance does the turtle cover before reaching that maximum speed? v i = 0 a = 0.05m/s 2 t = 3sec v f = 0.15m/s r i = 0 r f – r i = v i t + ½ at 2 r f = 0.225m 3. Prof. Kram plans to repair his metal roof this weekend. There was significant storm damage from a snowstorm last winter. One section of the roof has an angle of 0.6 radians. If he slips and slides reaching a velocity of 4 m/sec along the roof just as he reaches the edge, what are the horizontal and vertical components of his velocity? Make a simple sketch, and pay attention to sign conventions. In subsequent weeks, we can calculate his bodily harm. |v| = 4m/s theta = 0.6rad v x = cos0.6(4m/s) v y = sin0.6(4m/s) v x = 3.3m/s v y = -2.26m/s 4. The canine long jumpers we showed you on video jumped just less than 8 meters before they hit water.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
