Question1
Jim's dog Sparky runs 45.0 northeast to a tree, then 70.0 west to a second tree, and at last 25.0 south to a third tree.
1) Compute Sparky's net displacement vector.
Enter the east and north components of the net displacement
2) determine magnitude of Sparky's net displacement. (Meters)
3) compute direction of Sparky's net displacement (degrees)
Question2
A curve of radius 54 m is banked for a design speed of 100 km/h. If coefficient of static friction is 0.30 (wet pavement), at what range of speeds be able to a car safely make the curve? Find out min and max?
