m is the mass
C is the heat capacity of the material
ΔT is the temperature change
The position of the object with respect to the ground is 8.48 m
The given parameters;
height of the building, h = 24 m
time of motion, t = 1.78 s
The distance traveled by the object after 1.78 s is calculated as;
The position of the object with respect to the ground is calculated as;
Thus, the position of the object with respect to the ground is 8.48 m
