The acceleration of the reciprocating roller follower when it has contact with the straight flanks of the tangent cam, is given by

A. ω². (r₁ r₂). (1 - cos² θ)

B. ω². (r₁ + r₂). (1 + cos² θ)

C. ω². (r₁ + r₂). [(2 - cos² θ)/cos³ θ]

D. ω². (r₁ - r₂). (1 - sin² θ)

Please do not use chat terms. Example: avoid using "grt" instead of "great".
