A crate has a mass of 6kg. Using the fact that the acceleration due to gravity is g=9.8 m/s2, how much work is done in lifting the crate 3m, in Joules? Round answer to one decimal place if necessary.

Sagot :

Work done = force applied * distance covered

Force = mass * acceleration

Therefore, Work done = mass * acceleration * distance covered

Parameters:

mass = 6kg

acceleration = 9.8m/s2

distance = 3m

Substitution:

Work done = 6 * 9.8 * 3

Work done = 176.4J (to 1 decimal place)
