a. The particle has position vector


b. Its velocity vector is equal to the derivative of its position vector:

c. At
, the particle has position


That is, it's 56.0 m to the right and 49.0 m up relative to the origin, a total distance of
away from the origin in a direction of
relative to the positive
axis.
d. The speed of the particle at
is the magnitude of the velocity at this time:


Then its speed at this time is

The answer is C. 35m/s because there is no direction
The design that would be used to make an efficient commercial vehicle chassis that has many realistic truck components is:
- Strength
- Adequate bending stiffness
- Maximum stress
- Deflection, etc
<h3>What is a Chassis Frame?</h3>
This refers to the main vehicle structure of a car that bears all the main stress that other components are attached to.
Hence, we can see that to make a good design for an efficient commercial vehicle chassis that has many realistic truck components, we would have to consider various factors such as handling maximum stress, maximum equilateral stress, and deflection.
