Question

1. A crane lifts 300.5 kg to a platform that is 1.9 m above the ground. How much work is done? (HINT: 1" convert the
mass (kg) into newtons (force), then solve for work.)

Answer 1

Answer:

Work = 5595.31J

Explanation:

Mass = 300.5kg

Distance (h) = 1.9m

Acceleration due to gravity (g) = 9.8m/s²

Work done on an object is the product of the force applied over the distance the object is moved.

Work = force * distance

Force = mass * acceleration (a or g)

F = m* g

F = 300.5 * 9.8

F = 2944.9N

Workdone = force *distance

Work = 2944.9 * 1.9

Work = 5595.31J

The work done is 5595.31J
