Explanation Write the expression for width of the beam as it enters the transparent plastic from Figure P25.9. w = 2 b + a Here, w is the width of the beam, a is the distance between the two rays at the information centre, and b is the distance from the right end to the centre of the peak. Rearrange the above equation. b = w − a 2 (I) Write the expression for angle θ 2 from the left side right angled triangle in Figure P25.9. tan θ 2 = b t Here, θ 2 is the angle of refraction, and t is the thickness. Rearrange the above equation to find θ 2 . θ 2 = tan − 1 ( b t ) (II) Write the expression for Snell’s law of refraction. n 1 sin θ 1 = n 2 sin θ 2 Rearrange the above equation to find θ 1 . sin θ 1 = n 2 sin θ 2 n 1 θ 1 = sin − 1 ( n 2 sin θ 2 n 1 ) (III) Given that the refractive index of the air n 1 = 1.00 , and the refractive index of the plastic n 2 = 1.55 . Apply the above condition in equation (III), to find θ 1 . θ 1 = sin − 1 ( 1

Two objects get pushed by the same magnitude of force. One object is 10x more massive. How does the rate of change of momentum for the more massive object compare with the less massive one? Please be able to explain why in terms of a quantitative statement found in the chapter.

A box is dropped on a level conveyor belt that is moving at 4.5 m/s in the +x direction in a shipping facility. The box/belt friction coefficient is 0.15. For what duration will the box slide on the belt? In which direction does the friction force act on the box? How far will the box have moved horizontally by the time it stops sliding along the belt?
