I'm stuck between B and CIn the problem, I know the potential energy increases because the height increases.A block is at the bottom of a frictionless ramp and is given a kick so that it has some initial velocity and starts to slide up the ramp. Thereis no air resistance. Which of the following is true of the energy of the block as it slides?(A) Its potential energy will increase; its kinetic energy will decrease. (C) Both its potential and kinetic energies will increase.(B) Its potential energy will decrease; its kinetic energy will increase.(D) Both its potential and kinetic energies will decrease.

What integer values satisfy both inequalities? 2 < x < 3 2 x 2 please answer the questions Distance between Train 1 and Train 2 = 95 miles.Average speed of Train 1 = 45 mph.Average speed of Train 2 = 60 mph.If both trains leave at the same time and travel toward each other but on parallel tracks, in how much time will their engines be opposite each other? (Hint: When the engines are opposite each other, together the trains will have traveled 95 miles. Their relative speed of travel is the sum of their respective speeds, or 105 mph.)Travel time = hours.
