Hi There,

I'm having trouble with these physics question in my homework:

1. An object of mass 1.5kg rests on a slope making an angle of 30 degrees, with the horizantal calculate:

a) the frictional force and

b) the normal reaction acting on the object. Gravitational field strengh = 9.8N/kg

2. Two tug boats pull a ship so that it moves with a constant velocity. Each of the tugs produces a tension T at an angle of 28 degrees to the direction the ship is moving. The drag on the ship is 220kN. Calculate T.

I would be really grateful if you go could help me with this, its driving me nuts...oh and by the way with question 1, I worked out the normal force, which I think is what I had to do and got 1.3N (1dp)...after that I got stuck..especially with the whole coefficent friction :yuck:
