Momentum
Two balls roll toward each other on a frictionless floor. The red ball has a mass of and a speed of The blue ball has a mass of and a speed of If the balls stick together after the collision, determine the (approximate) final velocity of the balls.
A bumper car travels at due east. It hits an identical bumper car traveling due north at If the two cars lock bumpers and stick together, what is the approximate resulting speed of the cars?
An astronaut floating still in space has a total mass of including his weight and all his equipment. He throws a wrench with a speed of What is the resulting speed of the astronaut?
Ball of mass is rolling on a frictionless horizontal floor at It collides head-on with ball of mass which is initially at rest. If we let and denote the respective velocities of balls and after the collision, in which of the following situations are the linear momenta conserved?
Define the initial direction that ball moves in as positive direction.
Object of mass moves with a velocity of toward a stationary object of mass After the impact, objects and move off in directions that form and angles with the initial direction of object respectively. Assuming that the system is entirely frictionless, what is the speed of object after the collision?
