a partical moves on circular of radius 30cm its liner speed is given by v 2t find the radial and tangantial acclartion at t 3sec

Answer 1

I am going to assume that you could not type = signs

R = 0.30 meters
Vt = 2t

at t = 3 s
Vt = 6 m/s

dVt/dt = 2 m/s^2

so
At = 2 m/s^2

Ar = Vt^2/R = 36/.3 = 360/3 = 120 m/s^2
