1. A cylindrical can has a volume of 400pi cubic centimeters. The material for the top and bottom costs 3 cents per square centimeter. The material used for the vertical surface costs 2 cents per square centimeter. Express the cost of the materials used to make the can as a function of the radius r.

2. A power station and a factory are on opposite sides of a river 2 km wide. A power line must be run from the power station. It costs $25.00 per meter to run the cable in the river and $20.00 per meter on land. Express the total cost as a function of x.

1.) A 1.00kg object is observed to have an acceleration of 10.0m/s^2 in a direction 30.0° north of east. The force F2 acting on the object has a magnitude of 5.00N and is directed north. Determine the magnitude and direction of the force F1 acting on the object.

2.) A frictionless plane is 10.0m long and inclined at 35.0° . A sled starts at the bottom with an initial speed of 5.00m/s up to the incline. When it reaches the point at which it momentarily stops, a second sled is released from the top of this incline with an initial speed vf. Both sleds reach the bottom of the incline at the same moment. (a) Determine the distance that the first sled traveled up the incline. (b) Determine the initial speed of the second sled.
