PHY 1001 Unit One – Motion Mathematical Assignment 1. Calculate the velocity of a car (in m/s) that starts from rest and accelerates at 5 m/s 2 for 6 seconds. Key Idea Stock of Data and Velocity a=5m/s^2 time =6 seconds The speed of something in a given direction. Solution 0 + 5x = y 0 +5(6)= 30 m/s Sanity Check 6(5) = 30 + 0 = 30 2. Calculate a pendulum's frequency of oscillation (in Hz) if the pendulum completes one cycle in 0.5 s. Key Idea Stock of Data and Frequency- how often something occurs A pendulum completes one cycle in 0.5 s=> T = 0.5s f = 1/T = 1/.5 = 2Hz Solution

1/0.5= 2 Sanity Check 1 divided by a half is 2 3. Irina dives from a 25-meter high platform into a water (see diagram ). a. Irina’s acceleration as she is falling from the platform. _______3m/s__ What hypothesis(s) must you make in order to state this value as the acceleration? Explain. Irina must be at least a teenager putting her at around 100-140 lbs not including gravity she should be falling at a decent speed c. Use kinematic equations to fill in the table below.

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.

• 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.
