Question

Movers transport a refrigerator with a mass of 113 kg the distance of 22 m from your kitchen to their truck. As the movers move the refrigerator up a ramp, they momentarily slip back 4 meters. The slippage results in:__________.

Answer 1

additional work of 4,429.6 J

Step-by-step explanation:

step 1. work done in transporting the refrigerator to a distance of 22 m = F*S

= m*g*s

= 113*9.8*22

= 24,362,8 J

step 2. When the mover and the refrigerator momentarily slip back 4 meters

work done in transporting the refrigerator back to 4 m = 113*9.8*4

= 4,429.6 J

step 3. The slippage results in additional work of 4,429.6 J
