Radial and Tangential Acceleration

[duey_rando]

I can't figure out how to do this for the instant time or with the limited information.

A particle moving clockwise in a circle of radius 2.5 m at a certain instant of a time. For that instant, find (a) the radial acceleration of the particle (b) the speed of the particle and (c) it tangential acceleration.

Radius= 2.5m
Theta= 30 degrees
a= 15.o m/s^2

hi duey_rando! welcome to pf!

do you mean that it starts with speed 0, and accelerates at 15.0 m/s² ?

if so, find the speed first, then use the standard formulas to find the radial and tangential acceleration
