1)an object moves in a circular path of radius 10 m with a constant speed of 30m/s. What is the magnitude and the direction of the acceleration?
2.) a horizontal, 10m plank weighs 100N. it rests on two supports that are placed 1.0m from each end. how close to one end can an 800N person stand without causing the plank to tip?(hint: what happens to the normal force on the support at the opposite end of the plank from the man when the board tips?)

An object moves in a circular path at a constant speed. What is the relationship between the directions of the object's velocity and acceleration vectors? The velocity and acceleration vectors point in opposite directions. The velocity and acceleration vectors are perpendicular. The velocity vector points in a direction tangent to the circular path. The acceleration is zero. The velocity vector points toward the center of the circular path. The acceleration is zero. The velocity and acceleration vectors point in the...

An object moves in a circular path with constant angular speed. Compare the direction of the object's tangential velocity vector to its centripetal acceleration vector. A) Both vectors point in the same direction B) The vectors point in opposite directions C) The vectors are perpendicular D) Impossible. The acceleration is zero. Two objects with masses m1 and m2 are original a distance r apart. The magnitude of the gravitational force between them is F. if BOTH masses are doubled, and...
An object of mass m moves at a constant speed v in a circular path of radius r.
An object of mass m moves at a constant speed v in a circular path of radius r. The force required to produce the centripetal component of acceleration is called the centripetal force and is given by F=mv2/r. Newton's Law of Universal Gravitation is given by F=GMm/d2, where d is the distance between the centers of the two bodies of masses M and m, and G is a gravitational constant. The speed required for circular motion is v= √(GM/r). Use the...
