Data and Graph have been given. A. Solve X-Motion: x [grids] vs. t [flashes] -> the slope of this graph corresponds to the x-axis component of velocity Vx.

B. Solve Y-Motion: Vy vs t. The slope of this graph corresponds to y-component of acceleration, and Ay= -g

C. Calculation of the slope of the best fit line for both graphs.

D. Compare slope of the Vy graph to 980cm/s^2 (acceleration due to gravity)

If element x has 99 protons how many electrons does it have

Two carts, one of mass 2m and one of mass m, approach each other with the same speed, v. when the carts collide, they hook together. assume that positive momentum is to the right. which graph best represents the momentum of both carts over time, before and after the collision?

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
