Which of the following describes a car that is accelerating? A car going around a circular track at a steady 30 miles per hour A car driving on a straight uphill road at a steady 30 miles per hour.

A car going around a circular track at a steady 30 miles per hour.

Explanation:

Acceleration occurs anytime an object's speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous.

A car going around a circular track at a steady 30 miles per hour changes direction as its moves in that circular path that is, even when a body has constant velocity, it changes direction and velocity is a vector quantity which depends on direction.

A car driving on a straight uphill road at a steady 30 miles per hour. Since it is constant , no change in velocity, no acceleration. Therefore acceleration is said to be zero,

50 inches should be the resultant vector

like poles repel so keep pushing north to north and repels funny to see this
