Question

# Please help me with these following physics I questions!

rad/s (b) Determine the tangential speed at a point 3.10 cm From its center.

m/s (c) Determine the radial acceleration of a point on the rim.

magnitude km]:2

direction —Sa|act— 9 (d) Determine the total distance a point on the rim moves in 2.02 s.

m quot;admin? ii (a) The ﬁshing pole in the ﬁgure below makes an angle of 20.0 with the horizontal. What is the torque exerted by the ﬁsh about an axis perpendicular to the page and passing through the angler’s hand if the ﬁsh .9

pulls on the ﬁshing line with a force F = 90 N at an angle 37.0D below the horizontal? The force is applied at a point L = 2.20 m from the angler’s hands. (Enter the magnitude in N – m, accurate to at least the

nearest integer.) magnitude N – m

A direction (b) What If? To reel in the ﬁsh, the angler now pulls back on the ﬁshing rod, increasing the angle it makes with the horizontal to 38.0. If the ﬁsh still applies the same force in the same direction, what is the

increase in the torque exerted by the ﬁsh about an axis perpendicular to the page and passing through the angler’s hand? (Enter the magnitude in N – m.) N-m Need Help? ii
