QUESTION 1 A plane is flying horizontally with a constant speed of 55.0 m/s when it drops a rescue capsule. The capsule lands on the ground 12.0 s later. a) Find the height from which the capsule had dropped. 705. 6 m (3 marks) b) Just before the capsule hits the ground, find i) horizontal component of its velocity, 55m/ 5 (1 mark) ii) vertical component of its velocity, and - 17.6 m/ S (2 marks) iii) final speed and direction of the capsule relative to the positive x-axis 129.8 m /s, 295.10 (5 marks) c) How would your answer to part b) iii) change if the constant speed of the plane is increased? Explain. (4 marks) QUESTION 2 a) State Newton's First Law. (2 marks) b) A 20-kg crate is being pulled to the right across a horizontal floor at constant speed by a force of 35 N at an angle, above the horizontal. The friction force on the crate is 20 N. i) Sketch the free body diagram and label all the forces acting on the crate. (2 marks) ii) Determine the angle, e the pulling force makes with the horizontal. 55.2 (3 marks) iii) Find the magnitude of the normal force that the ground exerts on the crate. 167. 3N (3 marks) iv) Find the coefficient of the friction between the crate and surface of the floor. 0.12 (3 marks) c) Briefly describe an application of friction that happens daily between two surfaces in contact.
