Answer:
T = 570 N
Explanation:
Given that,
The gravitational force acting on a bucket of water = 525 N
Net force in the Y direction is 45 N
We need to find the magnitude of the force of tension. It can be calculated as :
45 = T - 525
T = 525 + 45
T = 570 N
Hence, the force of tension is 570 N.
To determine the force of the system, we use Newton's Second Law of motion which relates force and mass where they are directly proportional and the constant of proportionality is the acceleration. We calculate as follows:
F = ma
F = 10.41 kg ( 6.5 m/s^2 )
F = 67.67 kg m / s^2 or N
Answer:
<h2>3.00m high</h2>
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.
