## Homework Statement

is 1222.5i 1 20.2j2 m/s . For that instant, (a) sketch a vector diagram showing the components of its acceler- ation, (b) determine the magnitude of its radial accel- eration, and (c) determine the speed and velocity of the ball.

42. A ball swings counterclockwise in a vertical circle at

the end of a rope 1.50 m long. When the ball is 36.9°

past the lowest point on its way up, its total acceleration is is -22.5i +20.2j m/s2 . For that instant, (a) sketch a vector diagram showing the components of its acceler- ation, (b) determine the magnitude of its radial accel- eration, and (c) determine the speed and velocity of the ball.

## Homework Equations

a= acì + atj

## The Attempt at a Solution

If the total acceleration is given by -22

5ì + 20.2j m/s2 then isn't 22.5 is the radial acceleration and 20.2m/s2 is the tangential acceleration. I am confused can you please show me the vector diagram too
