Calculate the force with which
the body will fall on u.
Also calculate, the kinetic
energy, when body will be at height 6 ft. from ground.
(take g=9.8m/s, mass of
body=62 kg..)
F = mg = 62kg * 9.8N/kg = 607.6N.
d = 6Ft * (1/3.3)m/Ft = 1.82m.
PE = mgh = 62 * 9.8 * 1.82 = 1106 Joules.
To calculate the force with which the body will fall on you, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
The acceleration of an object in free fall near the surface of the Earth is equal to the acceleration due to gravity, which is approximately 9.8 m/s^2. Therefore, the force with which the body will fall on you can be calculated as:
Force = mass × acceleration
= 62 kg × 9.8 m/s^2
= 607.6 N
So, the force with which the body will fall on you is 607.6 Newtons.
Next, let's calculate the kinetic energy of the body when it is at a height of 6 ft (which is approximately 1.83 meters) from the ground.
The potential energy at a certain height is equal to the mass of the object multiplied by the acceleration due to gravity (9.8 m/s^2) multiplied by the height. We can then use this potential energy to calculate the kinetic energy.
Potential Energy = mass × g × height
= 62 kg × 9.8 m/s^2 × 1.83 m
= 1,080.348 Joules
The kinetic energy of the body is equal to the potential energy at that height since the body will convert its potential energy into kinetic energy as it falls.
Therefore, the kinetic energy of the body when it is at a height of 6 ft from the ground is approximately 1,080.348 Joules.
