Answer :
Final answer:
The work done to lift a 2000kg mass 1.5m high is calculated as the product of the gravitational force on the mass and the distance it is lifted. The result is 29400 J.
Explanation:
The question is about calculating the work done to lift a 2000kg mass 1.5m using a jack. In physics, work is calculated as the force required to move an object a certain distance. The gravitational force on the object can be calculated by multiplying the mass by gravity (approximated as 9.8 m/s2).
Thus, the force is 2000kg * 9.8 m/s2 = 19600N. The work done (W) is the force (F) times the distance (d), or W = F * d. Therefore, the work done to lift this mass is 19600N * 1.5m = 29400 J (Joules).
