A long 100 kg rope of length 240 m is laid out in a straight line next to the ice boat. Both Ted and the rope can slide without friction along the surface of the frozen lake. The rope is unattached to any object until Ted attaches the end of the rope to a winch which pulls the rope onto the boat at 120 m every minute, i.e., the entire rope is secured on the boat in two minutes. For the answers below assume positive refers to the right, negative to the left. ⊲ What is Ted’s position at the moment just after all the rope as been completely secured onto the ice boat?

The designers chose a banking angle such that at 150 mph, a car could travel around the track even in slick conditions when frictional forces between the tires and road would disappear. Vectors A-J have directions shown in the picture, with vector J pointing out of the page in the direction the car is moving and I pointing opposite the car’s velocity. Vectors D and H are perpendicular to the surface, while vectors B and F are parallel to the surface. Vectors A and E are horizontal, whileperpendicular to the surface, while vectors B and F are parallel to the surface....
