Explanation Given Info: Refractive index of the plastic wall is 1.61 and the refractive index of air and water are 1 and 1.33 respectively. The below figure shows the interaction of unpolarized sunlight with the plastic wall of a water tank after the interaction from the wall some of light enters the water Figure (I) Formula to calculate polarizing angle is, tan θ p = n p n a θ p is polarizing angle. n p is refractive index of plastic. n a is refractive index of air. Rearrange for θ p . θ p = arctan ( n p n a ) Substitute 1.61 for n p and 1 for n a to find. θ p = arctan ( 1.61 1 ) = arctan ( 1.61 ) = 58.1548 ° The angle of incidence is between air and water and its value is, θ i = 90 ° − θ p θ i angle of incidence. Substitute 58.1548 ° for θ p to find θ i

3.63 • Leaping the River II. A physics professor did daredevil stunts in his spare time. His last stunt was an attempt to jump across a river on a motorcycle (Fig. P3.63). The takeoff ramp was inclined at 53.0°, the river was 40.0 m wide, and the far bank was 15.0 m lower than the top of the ramp. The river itself was 100 m below the ramp. Ignore air resistance. (a) What should his speed have been at the top of the ramp to have just made it to the edge of the far bank? (b) If his speed was only half the value found in part (a), where did he land? Figure P3.63 53.0° 100 m 40.0 m→ 15.0 m

Please solve and answer the question correctly please. Thank you!!

You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 5.00 s after it was thrown. What is the speed of the rock just before it reaches the water 25.0 m below the point where the rock left your hand? Ignore air resistance.
