If the velocity of a particle is nonzero, can the particle's acceleration be zero? O yes...
Can you have zero velocity and non-zero average acceleration? And acceleration zero and nonzero velocity? Explain, using a vx versus t graph and give an example of said movement.
.4j A particle is moving with a velocity of U 7.4 The particle's acceleration is 0.18i-0.9j. +3 S At this instant the particle is moving along part of a curved path which can be estimated as a circle of radius R. This curving is provided by the component of acceleration perpendicular to the motion of the particle. What is the magnitude of the component of acceleration perpendicular to velocity? Answer in s2 Answer:

Rotational motion with a constant nonzero acceleration is not uncommon in the world around us. For instance, many machines have spinning parts. When the machine is turned on or off, the spinning parts tend to change the rate of their rotation with virtually constant angular acceleration. Many introductory problems in rotational kinematics involve motion of a particle with constant, nonzero angular acceleration. The kinematic equations for such motion can be written as and . Here, the symbols are defined as...

Can a vector have a component equal to zero and still have nonzero magnitude? A component is made up of a magnitude and distance, so if i have (3m, 0degrees) i have a vector moving in the x direction for tree meters, it is going in the zero degree direction for 3 meters. And if i have a component (0 , 45 degrees), i have no velocity going towards 45 degrees. I tried answering "No, because another component of the...
