2. Relevant equations

Hi guys, i am a new member here, and am really looking for some help.

My question is: A wheeled truck has a total mass when loaded of 1500 kg and is to be hauled up an incline of 1 in 1o (sine). g= 9.81 m/s2 and the coefficiant of friction between the wheeles and the incline surface is 0.05, A tractive force is applied from a vehicle through a tie-bar, sufficient to acceleration the truck from rest to a verlocity of 20 m/s in 10s.

Calculate:

a. The tractive force delivered through the tie bar during the acceleration

b. The total work done on the wheeled truck during this period

c. The average power expanded on the truck by the towing vehicle

d. The maximim power developed by the towing vehicle in order to accelerate the truck.

3. After trying these questions i have found my self more confused than what i was originally!

Thankyou for any help, will be much appreciated!!
