Please answer these review questions for my physics class. Thank you

Answer 1

27.

centripetal force is given as

F = m r w²

the value of angular speed "w" is same at all locations and mass "m" is also same

hence force depends on distance "r" from center. since at edge "r" is maximum , hence the centripetal force is maximum at edge

c. edge

26 .

a)

W = work done = change in kinetic energy

25.

T = time period = 0.072 sec

w = angular speed = 2 $\pi$ /T = 2 x 3.14/0.072 = 87.22 rad/s

r = radius = 0.29 m

speed is given as

v = r w = 0.29 x 87.22 = 24 m/s

24.

given that :

g_jupiter = 3 g_earth

multiplying both side by mass "m"

mg_jupiter = 3 mg_earth

W_jupiter = 3 W_earth

b) more than
