Explanation / Answer

Solution :-

part a )

angular velocity = w = d*theta/dt

w = 0.740t

at t = 5.80s

w = 4.292 rad/s

part b )

v = rw

v = 6.80* 4.292 = 29.2856 m/s

part c )

tangential acceleration = at = alpha *r

alpha = dw/dt = 0.74

at = 0.74 * 6.80 = 5.032 m/s^2

part d )

radial acceleration = ac = v^2/r

ac = (29.2856)^2/6.8

ac = 126.1245 m/s^2
