For a certain interval of time, an object is acted on by a constant non-zero force. Which of the following statements is true for this interval of time? (Select all that apply.) The object's velocity changes. The object is moving with constant velocity. The object's velocity can only increase. The object is at rest. The object is accelerating.
matlab question A certain object has a mass of 100 kg and is acted on by a force f(,) = 500[2-c" sin(5m)] N. The mass is at rest at t-0. Determine the object's velocity at t = 5 s. A certain object has a mass of 100 kg and is acted on by a force f(,) = 500[2-c" sin(5m)] N. The mass is at rest at t-0. Determine the object's velocity at t = 5 s.
An object moving in the *x direction experience an acceleration of *2.0 m/s^2- This mean the object is increasing its velocity by 2.0 m/s every second. travels 2.0 m In every second. is traveling at 2.0 m/s. is decreasing its velocity by 2.0 m/s every second. Suppose that an object is moving with a constant velocity. Which statement concerning Its acceleration must be correct? The acceleration is constantly increasing. The acceleration is a constant non-zero value. The acceleration is constantly...
KINEMATICS AND DYNAMICS 1. Velocity versus time graphs for five objects are shown below. All axes have the same scale. Which object had the greatest change in position during the interval? Time To the right is a graph of an object's position. Which sentence is the best interpretation of the motion of the object as shown by the graph? 2. A. The object is moving with a constant, non- zero acceleration. B. The object is not moving. C. The object...
A fishing boat starts from rest and has a constant acceleration. In a certain time interval, its displacement doubles. In the same time interval, by what factor does its velocity increase?
Consider the object in the figure above. There are two forces acting on it, which are in opposite in directions. These two forces are the only forces acting on the object. The object is moving to the right and has a constant velocity. (a) Is the object accelerating? Choose one answer only. O object is accelerating to the right O object is not accelerating O object is accelerating to the left (b) How do the two forces compare? Choose one...
1. The velocity of an object traveling along the x-axis changes from 20 m/s to 60 m/s in 10 seconds. What was the displacement that occurred during this time? 2. An object moving along the x-axis initially has a velocity of 60 m/s and is slowing rest? down at the rate of 4 m/s per second. How far (in meters) will it travel before coming to 3. An accelerating object travels 12 meters from rest in a certain time. How...
5. Starting from rest, a particle confined to move along a straight line is accelerated at a rate of 5.0 m/s Which one of the following statements accurately describes the motion of this particle? A) The particle travels 5.0 m during each second. B) The particle travels 5.0 m only during the first second. C) The speed of the particle increases by 5.0 m/s during each second. D) The acceleration of the particle increases by 5.0 m/s during each second....
14. At a certain instant, a partide-like object is acted on by a force F=8.0i+4.0j-2.0k (in N) while the object has a velocity given by V=4.0i-2.0k (in m/s). What is the instantaneous power at which this force does work on the object. A.28W B.40W C.36W D.32W E.24W
