Answer: 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:
kinetic energy = 338 joules
Explanation:
given data
mass = 4 kg
velocity = 13 m/s
to find out
kinetic energy
solution
we get here kinetic energy that is express as
kinetic energy = [tex]\frac{1}{2} \times m \times v^2[/tex] .................1
here m is mass and v is velocity
put here value and we get kinetic energy
kinetic energy = [tex]\frac{1}{2} \times 4 \times 13^2[/tex]
kinetic energy = 2 × 169
kinetic energy = 338 joules
