a diver is standing on the diving board. the diver has a mass of 85.0kg and has a gravitational potential emergy of 2.50x103 j standing on the diving board. determine how high the diver is above the water surface

3.00m high

Explanation:

Gravitational potential energy of the diver is expressed mathematically as

P = mgh

m = mass of the diver (in kg)

g = acceleration due to gravity (in m/s²)

h = the height of the diver above the water surface.

Given m = 85.0kg, g = 9,8m/s² and P = 2.50x10³ Joules, wecan determine how high the diver is above the water surface bu substituting the given values into the formula;

h = P/mg

h = 2.50x10³/85*9.8

h = 2500/833

h ≈ 3.00m

The diver is 3.00m above the water surface.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
