Problem 3. On a hockey table, pucks A and B of 170 g each impact according to the figure shown. If they collide at 0 and rebound along the indicated trajectories, determine the speed of each puck right after the crash. The discs float due to the air coming out of the table. therefore there is no friction.

A 2.7 kg block of wood sits on a frictionless table. A 3.0 g bullet, fired horizontally at a speed of 500 m/s, ges completely through the block, emerging at a speed of 220 m/s. What is the speed of the block immediately after the bullet exits?
Ball bearing manufacturing is quite an art! In order to make perfect spherical balls, the manufacturers let molten metal droplets to fall inside a tall tower (i.e. the shot tower) to solidify as they fall. If a ball bearing needs 2.75 seconds to solidify enough for impact, how tall (in m) must the tower be? Use 9.80 m/s2 for the local acceleration due to gravity and assume no significant air resistance.

NASA's Saturn V rockets that launched astronauts to the moon were powered by the strongest rocket engine ever developed, providing 6.77 ✕ 106 N of thrust while burning fuel at a rate of 2.63 ✕ 103 kg/s. Calculate the engine's exhaust speed (in m/s).

How much fuel would be needed for a 1000-kg rocket (this is its mass with no fuel) to take off from Earth and reach 1000 m/s in 30 s? The exhaust speed is 1000 m/s.
Check Your Understanding Suppose you have a macroscopic salt crystal (that is, a crystal that is large enough to be visible with your unaided eye). It is made up of a huge number of unit cells. Is the center of mass of this crystal necessarily at the geometric center of the crystal?
A rocket takes off from Earth and reaches a speed of 100 m/s in 10.0 s. If the exhaust speed is 1500 m/s and the mass of fuel burned is 100 kg, what was the initial mass of the rocket?
From what might be a possible scene in the comic book The X-Men, the Juggernaut (mJ) is charging into Colossus (mC) and the two collide. The initial speed of the Juggernaut is vJi and the initial speed of Colossus is vCi. After the collision, the final speed of the Juggernaut is vJf and the final speed of Colossus is vCf as they each bounce off of the other, heading in opposite directions. a. What is the impulse experienced by the Juggernaut? b. What is the impulse experienced by Colossus? c. In your own words, explain how these impulses must compare with each other and how they are related to the average force each superhero experiences during the collision.
A Small pickup truck that has a caliper shell slowly coasts toward a red light with negligible friction. Two dogs in the back of the truck are moving and making various inelastic collisions with each other and the walls. What is the effect of the dogs on the motion of the center of mass of the system (truck plus entire load)? What is their effect on the motion of the truck?
At the centre of a circular ice rink, a 82.0 kg ice skater moving 2.25 m/s north hits and grabs onto a 57.0 kg ice skater who had been traveling west at 4.55 m/s. If the skaters hold onto each other and the rink has a 37.0 m diameter, what is the amount of time for the skaters to reach the edge of the rink?
Problem 1: The puffer fish (tetradontiade) can employ a defense mechanism whereby it fills its stomach with water until the fish is almost spherical in shape. The shape, in conjunction with its external spines, are a significant deterrent to predators. Suppose that a puffer fish takes in water until its mass has increased by f = 1.52 times its initial mass. In this state, and initially at rest, the puffer fish expels the water with a speed s in one direction, while the fish recoils in the opposite direction at a speed v. For this problem neglect the drag-force effects of the surrounding ocean water. Part (a) Write an expression for v/s in terms of f. Part (b) What is the numerical value of your answer to part (a)?
