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...

To understand two different techniques for computing the torque on an object due to an applied force.Imagine an object with a pivot point p at the origin of the coordinate system shown (Figure 1). The force vector F⃗ lies in the xy plane, and this force of magnitude F acts on the object at a point in the xy plane. The vector r⃗ is the position vector relative to the pivot point p to the point where F⃗ is applied.The torque on the...

Exercises 1. Suppose a force acts on a 4.00 kg object in the x-direction. The force varies with time and is given by F(t)12.0t3 - 8.00 N. At t -0, the object has a velocity of 3.00 m/s in the positive x-direction. Use the impulse-momentum theorem to find the object's velocity after 2.00 s. 2. In a lab experiment, a spring gun projects a metal sphere. The sphere leaves the spring gun with a velocity of 3.00 m/s in the...
