We have to covert 512 cal of heat in kilo joules.
As, 1 cal = 0.004184 kJ = 4.184 joules.
Therefore,
Thus, combustion of a small wooden match produces approximately ( in kilo joules ) is 2.142 kJ .

Answer:
Both will reach to same height
Explanation:
Here we can see that friction is to be ignored
so we can say that work done by all the non conservative forces is change in mechanical energy
Since all non conservative forces here is zero
so mechanical energy is conserved here
so here we can say that sum of initial kinetic energy and potential energy = sum of final kinetic energy and potential energy
So we will have
now maximum height is given as
so here we can say that greatest height will be independent of the mass so they both will reach at same height
