Explanation / Answer

23) Jupiter radius is about 10 times Earth Radius .

24)    mg

25)     speed = 50 * 60 = 3000 m/sec

26)    Length of plane = 1/2 * 2 * 3 * 3 = 9 m

27)    follow a circular path .

28) the same as the force applied to the block .

29)    mass of lamb = 110/10 = 11 kg

30)    resultant speed = 20 km/hr
