Work and Power Required to Lift a Load

Problem Statement

In a space where gravitational acceleration $g$g acts downward, an object of mass $m$m is lifted from the ground to height $h$h at a constant speed. Find the work $W$W done by the lifting force on the object. Then find the power $P$P when this lifting operation takes time $t$t.

Constraints

• Mass $m = 25\ \text{kg}$m=25 kg
• Gravitational acceleration $g = 9.8\ \text{m/s}^2$g=9.8 m/s2
• Height $h = 12\ \text{m}$h=12 m
• Time $t = 14\ \text{s}$t=14 s

Input Format

Find the value of power $P$P and give the answer as a positive integer.
