Answer:
5000 J
Explanation:
Given that,
Weight of Danny Diver, F = 500 N
He steps off a diving board 10 m above the water
We need to find the kinetic energy of the water with which it hits. Let its is K. It is given by :
E = mgh
Where g is acceleration due to gravity
So, he hits the water with kinetic energy of 5000 J.
Answer:
82.01m
Explanation:
Using the formula:
R^2=A^2+B^2
R= √ A^2+B^2
Where R= displacement
A=50m
B=65m
R= √ 50^2+65^2
R= √ 2500+4225
R= √ 6725
R=82.01m
