Question

the Coral S. cceleration of a point on the perimeter of a bicycle wheel of ofa bike is movh force a e that a jet plane's pilot, pulling out of a vertical dive, can 16. What is the centripetal the when can stand is about seven times his weight. What is the 70.0 cm 1l.l meters tolerate at a speed of 250.0 m/s ? orbit a planet in nearly circular orbits. Moon A has orbital radius R, and moon B has orbital 4 sTwo mons xb adus4R. Moon A takes 20.0 days to complete one orbit. How long does it take moon B to complete an orbit? 18. Two moons orbit a planet in nearly oys low circular orbit about the earth (i.e., it just skims the surface of the long does it take to make one revolution around the earth? o 0 cm 19. A satellite is in a earth). How Earth's radius: 6380 km 1.4 hours three. 20 Find the gravitational fore on sphere A due to the other three. 60.0 cm 25.0 cm 25.0 cm 60.0 cm Sphere A & C are 10.0 kg, sphere B &D; are 20.0 kg 21. A car is rounding a banked curve at an angle . Draw a free body diagram, including friction, of the car rounding the banked curve. Using your free body diagram, write a mathematical equation for Fe

Explanation / Answer

16) centripital accelarartion, ac = vt2 / r

r=radius of tyre

vt= velocity of bike

here r=70 cm= 0.7m

and vt= 8m/s

hence ac= 8*8/0.7 =91.4 m/s2
