Explanation:

kinetic energy = ½mv²

1800 = ½ × m × 11.2²

1800 = ½ × m × 125.44

3600 = 125.44m

m = 3600/125.44

m = 28.7 Kg

allsm [11]
<span>A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds; or through the sharing of electrons as in covalent bonds. The strength of chemical bonds varies considerably; there are "strong bonds" or "primary bond" such as metallic, covalent or ionic bonds and "weak bonds" or "secondary bond" such as Dipole-dipole interaction, the London dispersion force and hydrogen bonding.</span>
