The horizontal distance from the base of the vertical cliff is 
Generally the horizontal speed at the top is mathematically represented as

=> 
=> 
Answer:
a) centripetal force = m v^2 / R = 329 * (29.6 m/s)^2 / 183
F = 1580 Newtons
b) normal force = gravitational force - F = 329 * 9.8 - 1580 = 1640 N
Answer:
2.Scientists discovered new evidence to support their theories.
3.Scientists discovered that old interpretations of data was incorrect.
4.Scientists used observations and mathematical data to solve problems in new ways.
Explanation: Here you go
Answer:
ΔT = 1.22*10^-3 °C
Explanation:
First, you calculate the potential energy of the bird when it is at 35 m high. The potential energy is also the mechanical energy of the bird in this case.

m: mass of the bird = 0.75kg
g: gravitational constant = 9.8m/s^2
h: height = 35m

All this energy is given to the water. You use the following formula in order to calculate the change in temperature:

m: mass of the water = 50kg
c: specific heat of water = 4186 J/kg°C
Q is equal to U (potential energy of the bird) because the bird gives all its energy to water. By doing ΔT the subject of the formula you obtain:

hence, the maximum rise in temperature is 0.00122 °C
