Karen and her friends are playing rounders in the park. Jennifer is standing at point J, which is 18 metres due north of point C, where Claire is standing. Sue is standing at point S, 52 east of south of Jennifer and 12.4 metres from where Jennifer is standing. (You may assume that all distances are at and in a straight line.) (a) Draw a diagram showing the points J, C and S, marking in the angle and the lengths...

Question 1 - 20 marks This question is based on your work on MỤ123 up to and including Unit 10. Katie likes to play volleyball. When she serves, the trajectory of the ball after she hits it can be modelled by the quadratic equation 295 where y represents the height in metres of the ball above the ground, and x represents the horizontal distance in metres of the ball from the position where it was struck by Katie. Assume that...

Question 5 15 marks You should be able to answer this question after studying Unit 10 A crate, initially at rest, is pushed along a straight line up a rough ramp that makes an angle of 18° with the horizontal. The magnitude of the pushing force is 33 N, in a direction parallel to and up the ramp, and the acceleration of the crate is 0.16 ms-2. The coefficient of sliding friction between the crate and the ramp is 0.35....

The combined mass of the climber and stretcher is 110 kg, and the slope makes an angle of 15° with the horizontal. The stretcher is held at rest by a rope that makes an angle of 20° with the upward slope. The stretcher is on the...

B. Describe what happens at a point on the surface of the water where: • a crest meets a crest . . a trough meets a trough a crest meets a trough For each of the above cases, describe how your answer would differ if the amplitudes of the two waves were not equal. Explain your reasoning. If the waves from two identical sources travel different distances to reach a particular point, the amplitudes of the waves from...

1 L, as a dynamical system (Notes from Assignment #2) We take our definition of dynamical system to be an "object" along with a specific set of modifications that can be performed (dynamically) upon this object. In this case, the object is a bi-infinite straight road with a lamp post at every street corner and a marked lamp (the position of the lamplighter). There are two possible types of modifications: the lamplighter can walk any distance in either direction from...
