Question 18 according to newton's second law of motion, the force acting on an object varies directly with the object's acceleration. suppose that a force of 18 n results in an acceleration of 6 /ms2 . if the object's acceleration becomes 9 /ms2 , what is the force?

When an object moves in uniform circular motion, the direction of its acceleration is a) in the same direction as its velocity vector. b) in the opposite direction of its velocity vector c) is directed toward the center of its circular path. d) is directed away from the center of its circular path. e) depends on the speed of the object.

If the textbook weighs 19.6 newtons on venus, what is the strength of gravity on venus?

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
