    Angular motion-centrifuge problem .

    Homework Statement : A centrifuge starts from rest and speeds up at 3400rpm after 50 seconds. a sample is at a distance of 37.5mm from the centre 1) find the angular acceleration 2) calculate the centripetal acceleration [/B] Homework Equations : v2 / r v = rω a = rω2 a=Λω/Λt 3. The...

    Scale reading in elevator with acceleration and constant velocity

    thanks for your help. i am understanding the concepts slowly. Where do i search on this website for textbooks. Would you know of any textbook that explains these concepts but are not to technical to understand.

    Scale reading in elevator with acceleration and constant velocity

    Question 3) if it is moving upwards at 4m/s for 5 seconds. Then there would be no acceleration as a=0 so the scale would read the same 1128 N would i need to show any working out instead of w=mg = 91.7* 9.8

    Scale reading in elevator with acceleration and constant velocity

    Homework Statement A person stands on a scale in a elevator at rest. The scale reads 900N. 1) what is the persons mass 2) the elevator accelerates up at 2.5m/s^2. What does the scale read now ? 3)The elevator then continues to move upwards with a steady speed of 4m/s for 5 seconds. What does...

    Aircraft velocity and direction to return to base

    Okay i think i understand from your diagram. this is because the resultant vector is from the start point to the end point, then you have drawn a triangle. Would my calculations be right in assuming the length of each side. then using pythagorean theorem and tan^-1 to find the angle.

    Aircraft velocity and direction to return to base

    would i connect the lines between west 41.7 km and east 12.48km to the base position therefore drawing a triangle ?

    Aircraft velocity and direction to return to base

    11.2km away using the pythagorean theroem. I understand i would be able to draw a clear triangle diagram and then find the angle and the distance.

    Aircraft velocity and direction to return to base

    I have converted all the answers to m/s i.e. 100km/hr /3.6 constant = 27.8m/s 25m/s 75km/hr /3.6 constant = 20.8m/s then converted the time to seconds 25 min = 1500s 1000s 10min=600s distance = speed *time = 27.8ms*1500=41.7km 25*1000=25km...

    Aircraft velocity and direction to return to base

    1.A aircraft leaves base and travels west at a speed of 100km/hr for 25 minutes, then turns right and travels north at a speed of 25m/s for 1000 seconds, then turns right and travels east at a speed of 75 km/hr for 10 minutes. The plane is asked to return to base. Determine the direction that...
