Question

1. A point-like object undergoes
circular motion at a constant speed.
The position vector of the object
measured from the center of the
circle *
has constant magnitude and hence is
constant in time.
has constant magnitude but is changing
direction so is not constant in time.
is changing in magnitude and hence is not
constant in time.
is changing both in magnitude and direction
and hence is not constant in time.

The data given below comes from 2006 NASA space shuttle mission flown by the space shuttle Discovery. Plot the following quantities as a function of time Altitude Velocity Acceleration The radial velocity of the space shuttle is the component of the velocity that points in the direction of the radius connecting the shuttle to Earth’s center. From your altitude versus time graph, estimate the radial speed at t= 40 s t=80 s t=120 s
6. Which of the following statements is true about nonuniform circular motion? Here are the choices: The tangential velocity changes in direction but not in magnitude. In a circular path, radial acceleration is directed toward the center of the circle. The tangential acceleration in addition to radial acceleration is present due to the changes of speed. The body moves with constant speed.
