The vector position of a 3.70 g particle moving in the xy plane varies in time according to r1 = (3î + 3ĵ)t + 2ĵt^2 where t is in seconds and r with arrow is in centimeters. at the same time, the vector position of a 5.65 g particle varies as r2 = 3î − 2ît2 − 6ĵt.
(a) determine the vector position of the center of mass at t = 2.60.
(b) determine the linear momentum of the system at t = 2.60.
(c) determine the velocity of the center of mass at t = 2.60.
(d) determine the acceleration of the center of mass at t = 2.60.
(e) determine the net force exerted on the two-particle system at t = 2.60.

i need the answer to this too but idk it ; -;

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
