A worker needs to move a box of heavy equipment from the ground to a platform 2 meters high. Rather than lift
the box, the worker can use one of two ramps. Ramp X is
7 meters long and Ramp Y is 3 meters long. Use RACE your response should be 6-7 sentences long

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

no simpler subs form complex ones. synthesise = make

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500
