A hammer is accelerated at 13 rad/s^2 at a radiius of rotation of 1.5 m. the tangential hammer speed is 20 m/s.

Question

a)Determine the angular velocity of the hammer
b)the magnitude of the radial component of its linear acceleration

c)the magnitude of the tangential component of its linear acceleration

Answer 1

a. C = pi*2r = 3.14 * 3 = 9.42 m.

V = (20/9.42) * 2pi = 4.25pi rad/s =
13.34 rad/s.
