Answer:

Work done is 2280 Joules.

Step-by-step explanation:

Work done can be found using the formula


W=Fs\\

where:
W is work done ( in Joules)
F is force ( in Newtons)
s is displacement ( in Meters)

Assuming we are on Earth, we can find the force acting on the object using the mass with the following:

Mass × 10 = Force

12.0 × 10 = 120N

Moreover, we can find displacement by simply subtracting the final distance from the starting distance:

22.0m - 3.00m = 19.0m

Therefore,


W = Fs


W = 120N ×
19m


W= 2280J
