4. Rotating Experiments (Non-Inertial Reference Frame) Imagine that you are on a large rotating disk, with perpendicular to the disk at its center. Assume that you know that the center of the disk is fixed and that no real forces act on anything on the disk (except gravity (pulling downward) and the normal force (upward), which cancel each other out). As sume that changes only in magnitude, and that the rate of this change is constant. Is it possible for...

Interactive Exercises 5.04: Newton's Second Law in Two Dimensions A piece of space equipment is to be observed in a deep-space reference frame, which we assume is an inertial frame. The equipment is initially at rest relative to this frame, and at t = 0, two forces Fi and F2 are applied to the object. Both forces are constant, with Fi acting in the +x direction and F2 acting in the ty direction. The magnitudes of the two forces are:...

understanding newton's law 1. An object cannot remain at rest unless which of the following holds? a. The net force acting on it is zero. b. The net force acting on it is constant and nonzero. c. There are no forces at all acting on it. d. There is only one force acting on it. which one is the answer? there can be more than one answer.... 2.

Question 2 According to Newton's Laws of Motion, if I throw a baseball in outer space - far from any other object- how will that ball move over time? (For the sake of this problem, let's neglect my mass) After the force of my hand no longer acts on the ball: Question 2 options: the ball will move forward, but it will gradually slow down and come to a stop once the force of my hand no longer acts on...

Answer all please
In all problems, neglect air drag and use g- 10 m/s2 when needed. 1. A car initially moving at 30 m/s in a straight direction, reduces its speed to 10 m/s in a time of 10 seconds. Calculate the distance travelled by the car. 2. A cannon positioned on a flat, horizontal ground shoots a shell with muzzle speed of 180 m/s. Calculate the maximum height reached by the shell if (i) It is shot in a...
