I found an answer from

Kinetic Energy Calculator

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/ 2*m) multiplied by the velocity squared. For example, if a an object with a mass of  ...

For more information, see Kinetic Energy Calculator


Kinetic energy is the energy that an object has as a result of its motion.

K.E = \frac{1}{2} mv^2

Where, m - mass of an object and v - velocity of the object

Step 1: Take note of the information provided.

Mass of the pumpkin m = 5.0 kg

Kinetic energy of the pumpkin K.E = 160 J

Speed of pumpkin v = ?

Step 2: Calculating the speed of the pumpkin

K.E = \frac{1}{2} mv^2

v^2 = \frac{2K.E}{m}

v = \sqrt{\frac{2*160}{5.0}}

v = \sqrt{64}

v = 8

Hence, speed of the pumpkin v = 8 m/s
