A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. It takes a time of 2.40 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . The fisherman sees that the wave crests are spaced a horizontal distance of 6.50 m apart. Required:
a. How fast are the waves traveling?
b. What is the amplitude A of each wave?

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
