    Suppose a new particle is discovered, and it is found that a beam of these particles passes undeflected through “crossed” electric and magnetic fields, where E = 471 V/m and B = 0.00151 T. If the electric field is turned off, the particles move in the magnetic field in circular paths of radius r = 2.89 cm.

    Determine q/m

    for the particles from these data.

    part 1 A bullet of mass 2 g moving with an initial

    speed 500 m/s is fired into and passes through

    a block of mass 6 kg, as shown in the figure.

    The block, initially at rest on a frictionless,

    horizontal surface, is connected to a spring of

    force constant 599 N/m. If the block moves a distance 0.68 cm to the

    right after the bullet passed through it, find

    the speed v at which the bullet emerges from

    the block.

    Answer in units of m/s.

    collision.

    Answer in units of J.

    part 1 A 580 kg mass is sliding on a horizontal frictionless surface with a speed of 9.5 m/s when

    it collides with a 82 kg mass initially at rest,

    up a frictionless track at 60◦

    from horizontalWhat is the speed of the two blocks immediately after the collision? The acceleration

    due to gravity is 9.8 m/s

    An 8 g bullet is fired into a 319 g block that

    is initially at rest at the edge of a frictionless

    table of height 1.1 m. The bullet remains in

    the block, and after impact the block lands

    1.7 m from the bottom of the table. Find the initial speed of the bullet. The

    acceleration due to gravity is 9.8 m/s ^2

    .

    Answer in units of m/s.

    A 4.15 g bullet is fired vertically into a 1.98 kg

    block of wood.

    The bullet gets stuck in the block, and the

    impact lifts the block 0.074 m up. (That is,

    the block — with the bullet stuck in it — rises

    0.074 m up above its initial position, and then

    falls back down.)

    Given g = 9.8 m/s ^2

    . What was the initial

    velocity of the bullet?

    Answer in units of m/s

    A rocket is fired vertically upward. At the

    instant it reaches an altitude of 2720 m and a

    speed of 296 m/s, it explodes into three equal

    fragments. One fragment continues to move

    upward with a speed of 250 m/s following the

    explosion. The second fragment has a speed

    of 476 m/s and is moving east right after the

    explosion.

    What is the magnitude of the velocity of

    the third fragment?

    According to the Guinness Book of World

    Records (1990 edition, p. 169), the highest

    rotary speed ever attained was 2010 m/s (4500

    mph). The rotating rod was 15.3 cm (6 in)

    long. Assume the speed quoted is that of the

    end of the rod.

    What is the centripetal acceleration of the

    end of the rod?

    Answer in units of m/s

    If you were to attach a(n) 2.29 g object to the

    end of the rod, what force would be needed to

    hold it on the rod?

    What is the period of rotation of the rod?

    An amusement park ride consists of a large

    vertical cylinder that spins about its axis fast

    enough that a person inside is stuck to the

    wall and does not slide down when the floor

    drops away.

    The acceleration of gravity is 9.8 m/s

    2

    .

    Given g = 9.8 m/s

    2

    , the coefficient µ =

    0.614 of static friction between a person and

    the wall, and the radius of the cylinder R =

    5.2 m. For simplicity, neglect the person’s

    depth and assume he or she is just a physical

    point on the wall. The person’s speed is

    v =

    2πR

    T

    where T is the rotation period of the cylinder

    (the time to complete a full circle).

    Find the maximum rotation period T of the

    cylinder which would prevent a 73 kg person

    from falling down.

    Answer in units of s.
