Q1. Consider the conical pendulum with an 80.0 kg bob on a 10.0 m wire making an angle of 5.00 with the vertical as shown. Determine (a) horizontal and vertical components of the force exerted by the wire on the pendulum and (b) radial acceleration of the bob.

Q2. A train 400 m long is moving on a straight track with a speed of 82.40 km/h. The engineer applies the brakes at a crossing, and later last car passes the crossing with a speed of 16.4 km/h. assuming constant acceleration, establish how long the train blocked the crossing. Disregard the width of the crossing.
