Question1
A fishing pole is 2.00 m long and inclined above horizontal at the angle of 20.0°. A fish is pulling on it with a force of 100N 37-degrees below horizontal. What is torque exerted by the fish about an axis perpendicular to the page and passing during the hand of the person holding the pole?
Question2
A wheel starts from rest and rotates with constant angular to reach angular speed of 15.0 rad/s in 3.0s. Find out the magnitude of angular acceleration of the wheel and an angle in radians through that rotates in this time interval.
Question3
