In Figure (1), a 3.50 g bullet is fired horizontally at two blocks at rest on a frictionless table. The bullet passes through block 1 (mass 1.34 kg) and embeds itself in block 2 (mass 2.06 kg). The blocks end up with speeds v₁ = 0.670 m/s and v₂ = 1.31 m/s (see Figure (2)). Neglecting the material removed from block 1 by the bullet, find the speed of the bullet as it (a) leaves and (b) enters block 1.

A proton with an initial speed of 1.73 ✕ 108 m/s in the +x direction collides elastically with another proton initially at rest. The first proton's velocity after the collision is 1.382 ✕ 108 m/s at an angle of 37.0° with the +x-axis. What is the velocity (magnitude and direction) of the second proton after the collision?
A curling rock of mass, m = 19.1 kg, travelling at 4.09 m/s to the right collides with an identical stationary rock.

Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.65 m/s, and bumper car 2 is traveling 77.7° south of west at 4.10 m/s. They collide and stick together, as the driver of one car reaches out and grabs hold of the other driver. The two bumper cars move off together after the collision, and friction is negligible between the cars and the ground. Car 2 W-OE Car 1 (a) If the masses of bumper cars 1 and 2 are 596 kg and 625 kg respectively, what is the velocity of the bumper cars immediately after the collision? magnitude m/s direction ° east of south (b) What is the kinetic energy lost in the collision?
The figure shows a glancing (not head-on) collision between two billiard balls (viewed from above). Ball 1 is initially moving with 2.0 m/s in the positive x direction; ball 2 is initially moving with 1.0 m/s in the opposite direction.

You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. Your own body mass is 59.1 kg. This time you drop a ball from a height of 1.93 m and it hits the floor 0.251 s after you drop it. This time you suspect you are on a rocket that has just left the surface of the Earth, and is still not too far above the ground. What do you deduce the rocket s acceleration to be? 82.4 m/s^2 51.5 m/s^2 71.1 m/s^2 61.3 m/s^2
