Can someone please help me answer this question ?

b 60 N force

Explanation:

The change in the momentum is given by the force•distance from the attached point. We don't have any distance, but apparently, the stick forces are being applied in each quarter of the stick, so let's use fractions of 4 to solve it:

150 N:

150•1/4 = 37.5

30 N:

30•2/4 = 30•1/2 = 15

60 N:

60•3/4 = 45

40 N:

40•4/4 = 40•1 = 40

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
