please ansa all A car travels around a curve with constant speed. The correct statement from the following is the car has an acceleration directed inward toward the center of the curve. the velocity of the car is constant. the car has an acceleration direction outward from the center of the curve. the car has zero acceleration. the car has an acceleration directed in the instantaneous direction of the velocity vector. A ball is whirled on the end of a...
Lab 4: Introduction & Instructions Centripetal Acceleration Introduction Velocity is a vector with both a magnitude and a direction. Since acceleration is a measure of a change in velocity over time, it seems reasonable that either the magnitude of the velocity vector could be changing, or the direction, or both. If magnitude is changing only, then the motion occurs in one dimension and the principles of algebra can be applied to the equations of motion. But suppose the opposite case...

O v oE 11AP1 My et A Ye Teeche Native people throughout North and South America used a bola to hunt for birds and animals. A bola can consist of three stones, each with mass m, at the ends of three light cords, each with length t. The other ends of the cords are tied together to form a Y. The hunter holds one stone and swings the other two stones above his head (see Figure a). Both these stones...
