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.
