Physics relationship
Let W1 represent the work required to accelerate an object on a frictionless horizontal surface from rest to a speed of v. if W2 represents the work required to accelerate the same object on the same surface from a speed of v to 2v, then which one of the following is the corre...

Math, due tonight!
Assume that all linear dimensions of an animal increase by 12%. Then the animal will have the same shape. How do the surface area, the volume and the weight (under assumption of constant specific gravity) increase? Give the percentage of the increase.

A 1500 kg car moves along a horizontal road at speed v0 = 21.9 m/s. The road is wet, so the static friction coefficient between the tires and the road is only µs = 0.302 and the kinetic friction coefficient is even lower, µk = 0.2114. The acceleration of ...
Physics Vectors
two vectors A and B have magnitude such that A>B. We do not know the directions of the vectors. however we can say that the magnitude of the sum A+B must be between? a) B and 2A b)A and A+B c) A-B and A+B d) A-B and A e) B and A+B
