A car manufacturer claims that its car can accelerate from rest to 28 m/s in 14 seconds. Find the average acceleration and the distance the car has traveled while in the process of stopping

A car is moving at 17.7 m/s when it begins to slow down with a deceleration of 2.5 m/s². How long does it take for the car to travel 80 meters as it slows down?

feedback control loop with a proportional controller has an open loop transfer function GOL = Kc/S(5S+1)²where time is in minutes. Tune for PID controller using Zeigler Nicholas settings.

Solve ∫0^t y''(τ)y'(t-τ)dτ=y(t),y(0)=y'(0)=20

a crusher and a crusher are connected to the same electric drive power 2700 kg / h of the material pass successively through the crusher and then the crusher. Sieve particle size analysis of feed, crusher product and mill product respectively indicated specific areas of 2.9, 103 and 865 m2 / kg. Calculate the horsepower required to operate the crusher-crusher assembly, if the crusher's energy efficiency is 20% and the crusher's energy efficiency is 25%. The Rittinger's number for material is 77.4 m2 / kJ.

a roller mill or ball mill with a diameter of 3.98 m operating at a net energy loss of 19.5% to reduce a particle with sphericity of 1 from size of 3.98 X10^-3 m to 199.9 X10^-6 m. Calculate the percentage load volume to operate at 70% of critical speed. The mill cannot be operating at more than 1.31m^3 load volume at any given time
