Ch. 1 1,5,9,19,29,31,33 P1.1 Prepare: The car’s motion is along the x -axis and it slows down after the skid begins. Solve: P1.5. Prepare: Displacement is the difference between a final position x f and an initial position x i This can be written as Δ = = f i , x x x and we are given that x i = 23 m and that Δ x = –45 m. Solve: Δ - f i = x x x Since we want to know the final position we solve this for f . x = + Δ = + - = - f i 23m ( 45m) 22m x x x Assess: A negative displacement means a movement to the left, and Keira has moved left from x = 23 m to x = uniF020 –22 m. P1.9. Prepare: We are asked to rank order three different speeds, so we simply compute each one according to Equation 1.1: = distance traveled in a given time interval speed time interval Solve: (i) Toy = 0.15m 0.060 m/s 2.5s (ii) Ball 2.3m = 4.2 m/s 0.55s (iii) Bicycle 0.60m = 8.0 m/s 0.075s (iv) Cat 8.0m = 4.0 m/s 2.0s So the order from fastest to slowest is bicycle, ball, cat, and toy. Assess: We reported all answers to two significant figures as we should according to the significant figure rules.
