Homework Statement
A particle is moving clockwise in a circle of radius 2.50m at a given instant of time.
I have to find radiant and tangential acceleration and the speed of the particle.
The acceleration vector is 15.0 m/s² and the angle between the radius and the acceleration vector is 30°
Homework Equations
a tangential=∆v/∆t
a radial =v²/r
a =√at²+ar²
θ=?
The Attempt at a Solution
I tried finding the acceleration components but I was not able to use the data given in a proper way. I'm sure there is an equation involving the angle but I'm not sure which one it is.
I would use θ=tan^-1( at/at) but it results in two unknowns . I'm stuck on this probably easy problem. I need someone who knows the right equations to use.
Thank you
