You have a rotating turntable affixed radially with four protruding pencils. The pencils were found to trip the photogate 32 times per second. The angular velocity is 8pieTwo light objects A and B are taped on top of the turntable at distances 4 cm and 12 cm respectively from the center. What are the tangential velocities of A and B
To find the tangential velocities of objects A and B, we can use the formula:
v = r * ω
where:
v is the tangential velocity,
r is the distance from the center,
and ω is the angular velocity.
For object A:
r = 4 cm
ω = 8π rad/s
v_A = 4 cm * (8π rad/s) = 32π cm/s
For object B:
r = 12 cm
ω = 8π rad/s
v_B = 12 cm * (8π rad/s) = 96π cm/s
Therefore, the tangential velocity of object A is 32π cm/s and the tangential velocity of object B is 96π cm/s.
