A ball of mass 1/2kg is moved in a vertical circle .when ball is at p .calculate tangential acceleration?
Answers
it has given that a ball of mass 0.5 kg (yep, 1/2 kg) is moved in a vertical circle.
To find : Tangential acceleration of ball at point P.
solution : ball makes 30° with the vertical.
so, component of weight along tangent, W = mgsin30°
at equilibrium,
F = mgsin30°
⇒ma = mgsin30°
⇒a = gsin30°
⇒a = 10 m/s² × 1/2 = 5 m/s²
Therefore option (3) is correct choice.
