Academics

Q1. A person walks 41° north of east for 2.20 km. How far would another person walk due north and due east to arrive at the identical location?

Q2. At time 0 a grinding wheel has an angular velocity of 30. It has a constant angular acceleration of 35 until a circuit breaker trips at time = 2.20. From then on, wheel turns through an angle of 428 as it coasts to a stop at a constant angular deceleration.
