James M asked: A mosquito sits on the tip of one blade of a spinning pinwheel, as the pinwheel is carried across the yard by a running child. The child runs at a constant velocity and direction. The pinwheel rotates with a period of T = 1.00 s. In your frame of reference standing at the barbecue grill, the mosquito has a velocity vector of [1.51 m/s - 42.1sin(2pit) cm/s]unit_vector_i + [-0.34 m/s]unit_vector_j – [42.1cos(2pit) cm/s]unit_vector_k.
What is the (constant) centripetal acceleration (in m/s2) experienced by the mosquito as it spins on the tip of the pinwheel? (If you choose to enter units with your answer, write the units as “m/s2″, “m/sq.sec.” or “m/s^2″.)
Thanks,
James
