a body of mass 5kg is thrown vertically upwards with a speed of 10m/s. what is its kinetic energy when its thrown? find its potential energy when it reaches at the highest point. also find the maximum height attained by the body[g=10m/s]

To find the kinetic energy of the body when it is thrown upwards, we can use the formula:

Kinetic Energy = (1/2) * mass * velocity^2

Given that the mass of the body is 5kg and the velocity is 10m/s, we can substitute these values into the formula:

Kinetic Energy = (1/2) * 5kg * (10m/s)^2
Kinetic Energy = 250 joules

Therefore, the kinetic energy of the body when it is thrown is 250 joules.

To find the potential energy when the body reaches the highest point, we need to know the maximum height attained by the body. We can calculate it using the formula:

Potential Energy = mass * gravity * height

Given that the mass is 5kg and the acceleration due to gravity (g) is 10m/s^2, we can substitute these values into the formula:

Potential Energy = 5kg * 10m/s^2 * height
Potential Energy = 50 joules * height

Now, to find the maximum height, we need to convert the kinetic energy at the highest point into potential energy. At the maximum height, the velocity of the body reaches zero. So, we can equate the initial kinetic energy to the potential energy at the highest point:

250 joules = 50 joules * height

Dividing both sides by 50 joules gives us:

height = 250 joules / 50 joules
height = 5

Therefore, the maximum height attained by the body is 5 meters.

In summary,
- The kinetic energy of the body when it is thrown is 250 joules.
- The potential energy at the highest point is 250 joules.
- The maximum height attained by the body is 5 meters.

need the answer

You should be aware that the formula for kinetic energy is:

K.E = (M/2)V^2

It equals the potential energy gained at the highest point. Therefore

M g H = M V^2/2

Solve for H. M cancels out.
