wo bricks, each of mass M, head directly toward each other on a frictionless surface und collide, as shown. Brick A has twice the speed as brick B. Which one of the following statements is true regarding the forces the objects exert on each other during the collision? 2v - A The magnitude of the force that A exerts on B is four times smaller than the magnitude of the force that B exerts on A. The magnitude of the force that A exerts on B is two times smaller than the magnitude of the force that B exerts on A. The magnitude of the force that A exerts on B is equal to the magnitude of the force that B exerts on A. The magnitude of the force that A exerts on B is twice as large as the magnitude of the force that B exerts on A. The magnitude of the force that A exerts on B is four times as large as the magnitude of the force that B exerts on A.

A 0.508 kg ball, initially moving with a speed of 3.3 m/s bounces off a wall and then moves with a speed magnitude half of its original directed in the opposite direction. If the ball is in contact with the wall for 5.8 m/s, what is the magnitude of the average force that the wall exerts on the ball? A. 147.32 N B. 433.55 N C. None of the above

Problem 2: A 10 grams bullet moving at 800 m/sec hits 1000 grams block of wood and stays inside the block. The block had been originally at rest and is free to move. Immediately after the collision the block-bullet system starts to move up a ramp that is incline at 30 degrees. The coefficient of kinetic friction between the block and the ramp surface is 0.30. How far up the ramp will the block and bullet system move after the collision before coming to rest?

A 0.250 kg toy car moving with a speed of 0.860 m/s collides with a wall. The figure shows the force exerted on the car by the wall over the course of the collision. What is the magnitude of the velocity, or final speed, of the car after the collision?

A certain carbon monoxide molecule consists of a carbon atom of mass mc = 14 u and an oxygen atom of mass mo = 18 u that are separated by a distance of d = 122 pm, where "u" is an atomic unit of mass. a. Write a symbolic equation for the location of the center of mass of the carbon monoxide molecule relative to the position of the oxygen atom. This expression should be in terms of the masses of the atoms and the distance between them.  b. Calculate the numeric value for the center of mass of carbon monoxide in units of pm.

Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1400 kg and was approaching at 5.00 m/s due south. The second car has a mass of 850 kg and was approaching at 16.0 m/s due west.   a. Calculate the final velocity (magnitude in m/s and direction in degrees counterclockwise from the west) of the cars. (Note that since both cars have an initial velocity, you cannot use the equations for conservation of momentum along the x-axis and y-axis; instead, you must look for other simplifying aspects.) magnitude m/sdirection ° counterclockwise from west   b. How much kinetic energy (in J) is lost in the collision? (This energy goes into deformation of the cars.)  J

An air track glider is moving along at a steady speed of 3.60 m/s when a force of 1.20 N is applied in the direction opposite to the motion of the glider for a time of 2.40 s. The force then steadily decreases at a rate of 0.60 N/s for the next 3.00 seconds. a. Find the total impulse b. the final speed of the 250-g glider.

An atomic nucleus suddenly bursts apart (fissions) into two pieces. Piece A, of mass m 4, travels off to the left with speed v4. Piece B, of mass mB, travels off to the right with speed v B.
