Some parasailing systems use a winch to pull the rider back to the boat. During the interval when is between 20° and 40° (where t = 0 at 0 = 20°), the angle increases at the constant rate of 2°/s. During this time, the length of the rope is defined by the relation- ship r = 600-5/2, where r and t are expressed in feet and seconds, respectively. Knowing that the boat is traveling at a constant rate of 15 knots (where 1 knot = 1.15 mi/h), (a) plot the magnitude of the velocity of the parasailer as a function of time, (b) determine the mag- nitude of the acceleration of the parasailer when t = 5 s.

please dinot copy paste from other web i need urgent A petrol engine produces 250 kW while using 1.014 kg of fuel per minute. The fuel has a lower heating value of 45000 kJ/kg, and the engine has bore of 100 mm and the stroke-to-bore ratio of 1.2. The clearance volume of the cylinder is 1.178×105 mm3. The friction power is found to be 10% of the power that engine produces. Sketch (your own) the simple neat and clean block diagram of the engine, clearly indicating the control volume and control surface, with all the given data displayed on it. For air take the value of g = 1.4. Determine the following: The brake thermal efficiency (hb, th ). The indicated thermal efficiency (hind,th ). The mechanical efficiency (hmech ). The brake engine efficiency (hb ). The indicated engine efficiency (hind ). (Hint: Engine efficiency is a function of how the ideal work or power is calculated. Frequently, the air-standard cycle is used for calculating the theoretical work.) Use standard symbols…
