a) A small rocket is launched vertically from rest and reaches a maximum altitude \"h.\" The acceleration is constant at 11 ms until the fuel burns out after 5.4 seconds Assuming that from the point of burnout onwards the rocket is traveling freely vertically upwards with constant deceleration: Take: g=9.81ms\" Determine the maximum altitude 'h'? b) An electric train accelerates uniformly from rest to reach 45 km/h in mins, after which the speed is kept constant. Determine the total time taken to travel 10 kilometers? ) A drop forge hammer used in manufacturing green trains falls from rest through a height of 5.4m on to a forging. Find the downward velocity of the hammer when it strikes the forging. [f the mass of the hammer is 450kg what is the work done by the forging and base plate in bringing the hammer to rest in a distance of 45mm? Evidence you must produce for this task + All working out making clear any formulae used, making clear what is being calculated * ALL UNITS MUST BE SHOWN Criterion reference Solve three or more problems that require the application of kinetic p and dynamic principles to determine unknown system parameters To achieve the criteria, you must show that you are able to
