Two carts collide in a perfectly elastic collision. Cart A has a mass of 0.8 kg and an initial velocity of 0.18 m/s. It hits cart B, which has a mass of 0.7 kg and an initial velocity of 0.11 m/s in the direction opposite to the direction of cart A. What is the final speed of each cart? If they make a completely inelastic collision, what would their final speed be?
Obtain grand mean and unadjusted means for the ANCOVA model where covariate, "xc", Treatment, "a", response, "y" are considered and calculate adjusted means given the estimates
All forms of energy can be classified as either kinetic or potential energy. How would you describe nuclear, electric, chemi-cal, biological, solar, and light energy, and why? For each of these types of energy, research what objects are moving and..

A proton accelerates from rest in a uniform electricfield of 670 N/C. At some later instant,its speed is 1.60 X106 m/s(nonrelativistic, because v is much less than the speed oflight). Find the acceleration of the proton.
What is the magnitude of the football's resultant displacement
