Two blocks sliding on a frictionless surface with the less massive block moving twice as fast as the more massive block. Eventually, the smaller block catches up and collides with it, and sticks. What is the speed of the two blocks after the collision given the speed of the more massive block is

Amaterial that provides resistance to the flow of electric current is called a(an) (1 points)

Gravity is pulling an object into the sun. the closer the object gets to the sun, the greater the gravitational force that acts on the object, increasing its acceleration. a line graph plotting the speed of the object against time would have which shape? a: straight line of positive slope b: curved line that slopes upward c: curved line that slopes downward d: straight line of negative slope
