4. What kinetic energy has a 4 kg shotput thrown with a velocity of 13 m/s?

338 joules

Explanation:

Mass of shotput = 4kg

velocity of shotput = 13 m/s

Kinetic energy = ?

Kinetic energy is the energy possessed by a moving body (shotput). It is measured in joules.

Thus, Kinetic energy = 1/2 x (Mass x velocity^2)

K.E = 1/2 x (4kg x (13m/s)^2)

K.E = 1/2 x (4 x 169)

= 0.5 x 676

= 338 joules

Thus, the kinetic energy of the shotput is 338 joules.

answer; protein;

thats a little if u want the answer just look it up on google thats what i do haha : )
