Question

What is the kinetic energy of a 2 kg snowball thrown through the air at 5 m/s?

Answer 1

Kinetic energy = 1/2mv^2 so, 1/2(2) is 1 square 5 to get 25 and multiply that by 1 and the kinetic energy is 25. 1/2(2)(5)^2

Answer 2

Answer:

Kinetic energy of the ball is 25 joules.

Explanation:

Mass of the snowball, m = 2 kg

Speed of the ball, v = 5 m/s

Let E is the kinetic energy of the snowball. The energy possessed due to the motion of an object is called its kinetic energy. Mathematically, it is given by :

$E=\dfrac{1}{2}mv^2$

$E=\dfrac{1}{2}\times 2\times 5^2$

E = 25 joules

So, the kinetic energy of ball is 25 joules. Hence, this is the required solution.
