Q2. (a) a particle of mass 3 moves under a force
f = 3e^2t i + 3t j − 9 k
the particle is initially at the origin with velocity
v(0) = 2i - k
(i) find its position for all t
(ii) what is the angle between the paths of the two balls after the collision?
(b) a snooker cue ball of mass m travels with velocity 3 i and collides with a second snooker ball with mass 2m at rest. after the collision the 2m ball moves with speed 1 m/s in a direction 60◦ to the original direction of the cue ball. (i) what is the final velocity of the cue ball?
(ii) what is the angle between the paths of the two balls after the collision?

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
