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
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
