An object traveling in the positive direction and
accelerating in the positive direction will speed up.
True or false?
And
two carts are traveling at the same speed in the same
direction. The first carts speed doubles in a specified time. The
second carts speed doubles in twice that time. The magnitude of the
average acceleration of the first cart is greater than the
magnitude of the average acceleration of the second cart.
True or false

The figure below shows an object initially
at point A traveling in the +x-direction. It turns in a circular
path at constant speed until it is traveling in the +y-direction at
point C. The quarter-circle arc from A to C is 201 m in length, and
the particle moves from A to C in 42.0 s. Point B on the path is
35.0° below the x-axis.

A car is traveling to the left, which is the negative direction. The direction of travel remains the same throughout this problem. The car's initial speed is 24.1 m/s, and during a 8.47 -second interval, it changes to a final speed of (a) 27.1 m/s and (b) 11.2 m/s. In each case, find the acceleration (magnitude and algebraic sign).
