Question

A 992.0-g iron meteor impacts the earth at a speed of 1447.0 m/s. If its energy is entirely converted to heat of the meteorite, what will the resultant temperature rise be? (The specific heat for iron is 113 cal/kg.C)

Answer 1

Kinetic energy of meteor is 0.5 mv^2. This is equal to
Heat absorbed of meteor Q = m C delta T.

Delta T is change of temperature.

Note that you have to convert cal to joules.

Answer 2

is it 2214 C

Answer 3

That looks correct, @Emineyy.

Answer 4

ok thanks:S
