Zanele,
If a object has a w of 1060 calculate the mass

physical 
Damon,
I do not understand the first question.
In general U = m g h
m in kilograms
g is about 9.81 m/s^2 on earth surface
h is height in meters above some reference level, probably the ground here.
If a object has a w of 1060 calculate the mass
m g = 1060 Newtons I assume
m = 1060 /9.81 in kilograms
