A.2000

B.5000

C.1500

D.15000

Answer 1

mu wildest guess is c 1500

Answer 2

B. 5000

Step-by-step explanation:

The tow rope should be strong enough so that it can overcome the frictional force and pull pallet without breaking. In question following data is given:

Weight of pallet = W = 6000lbs

Coefficient of friction = uK = 0.42

The tow rope required to pull pallet = (Weight of pallet) (Coefficient of friction)

= (W)( uK)

= (6000)(0.42)

= 2520 lbs

5000lbs is higher value than 2520lbs. Hence, if we will use 5000lbs tow rope it can easily pull the pallet.
