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:

additional work of 4,429.6 J

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

the average speed is 24.57 km/hr

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
