Just before it hits the runway it is moving at 76 m/s. The plane has a mass of 20,000 kg. The runway is 1.6km long and, obviously, the airplane needs to be stopped before it reaches the end of the runway. How large is the braking force the airplane needs to stop safely before the end of the runway?7) A ball is thrown in the air at an angle of 40°. If the maximum height it reaches is 10 m, what must be its initial speed? a) 17.46 m/s b) 21.78 m/s c) 304.92 m/s d) 474.37 m/s
- R4where År307-15f chnd B=-4.09+4.5s? 2-ナト A-307-258 what is the vector Sum7. An object travelling at 10.5 m/s on a horizontal surface approaches an inclined plane. Which plane would the objecttravel the HIGHEST on?a. A ramp with an incline of 20ob. A ramp with an incline of 25oc. A ramp with an incline of 30od. A ramp with an incline of 35oe. It will travel the same height on every ramp4. Show that the acceleration of any object down an incline where friction behaves simply (that is, where F* = Hk FN) is a = g(sin 0 – Hk Cos 0). Note that the acceleration is independent of mass and reduces to a = g sin ở when friction becomes negligibly small (4k = 0).
