a. Explanation Formula used: Consider the expression for acceleration. a x = Δ v x Δ t (1) Here, Δ t is the change in time. Δ v x is the change in velocity. Calculation: Refer Figure P2.63, for maximum acceleration of the person lies where the slope of velocity verses time graph will be maximum. Modify equation (1) for acceleration. a = v f − v i t f − t i (2) Here, v f is the final velocity. v i is the initial velocity. t f is the final time. t i is the initial time. Substitute 0.5 m s for v f , 30 ms for t f , 0 s for t i and 0 m s for v i in equation (2), a = 0.5 m s − 0 m s 30 ms − 0 s = 0 b. To determine The acceleration at t = 150 ms . c. To determine The distance travel in first 50 ms.

In the pivot assignment, we observed waves moving on a string stretched by hanging weights. We noticed that certain frequencies produced standing waves. One such situation is shown below: 0 ст Direct Measurement ©2015 Peter Bohacek I. 20 0 cm 10 20 30 40 50 60 70 80 90 100 Which Harmonic is this? Do NOT include units! What is the wavelength of this wave in cm with only no decimal places? If the speed of this wave is 2500 cm/s, what is the frequency of this harmonic (in Hz, with NO decimal places)?
