Acar starts from rest and moves around a circular track of radius 37.0 m. its speed increases at the constant rate of 0.440 m/s2. (a) what is the magnitude of its net linear acceleration 18.0 s later? (b) what angle does this net acceleration vector make with the car's velocity at this time?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
