2 1. A plane is flying horizontally at a speed of 72 m s -1. It is at a height of 102 m above the ground. When the plane is flying over an origin O, a parcel B is released . After some time, parcel B strikes a truck T of height 2.0 m, which is moving along a level road with a constant speed v. At the instant parcel B is released, the truck T is at a distance xo = 125 m from origin O. (a) Calculate the time of flight of parcel B before it strikes truck T. [3] parcel B plane 102 m 2.0 m

3 (b) On the same axes, sketch two graphs to show the variation with time t of the horizontal displacement x from the origin for parcel B and truck T. Label the graphs B and T respectively. Time t = 0 is the instant when parcel B is released from the plane. [2] (c) Using the graphs in part (b) or otherwise, calculate the speed v of truck T. [2] x / m t / s t = 0

4 2. An amusement park ride consists of a rotating circular platform 8.00 m in diameter. The child and the seat can be considered as a mass of 50 kg suspended at the end of 2.5 0 m light rope. When the system rotates, the rope make an angle θ of 28.0o with the vertical. Air resistance is negligible. (a) In the space below, draw a labelled free-body diagram of child A and seat. The child and seat can be considered as a 50 kg mass. [2] (b) Show that the radius of the circular motion of each child and seat is estimated to be 5.2 m. [2] rope 50 kg mass

5 (c) Calculate the speed of each child and seat. [3] (d) Calculate the tension in each rope. [2]

6 3. The diagram shows a mechanism for firing a ball of mass 25 g vertically into th
