Question

A woman is 1.7 m tall and has a mass of 50 kg. She moves past an
observer with the direction of the motion parallel to her height.
The observer measures her relativistic momentum to have a magnitude
of 2.6 × 10^{10} kg·m/s. What does the observer measure for
her height?

Answer #1

A woman is 1.6 m tall and has a mass of 55 kg. She moves past an
observer with the direction of the motion parallel to her height.
The observer measures her relativistic momentum to have a magnitude
of 2.7 × 1010 kg·m/s. What does the observer measure for
her height?

A woman is 1.6 m tall and has a mass of 55 kg. She moves past an
observer with the direction of the motion parallel to her height.
The observer measures her relativistic momentum to have a magnitude

An unstable nucleus of mass 1.7 ✕ 10−26 kg, initially at rest
at the origin of a coordinate system, disintegrates into three
particles. One particle, having a mass of
m1 = 2.6 ✕ 10−27 kg,
moves in the positive y-direction with speed
v1 = 5.4 ✕ 106 m/s.
Another particle, of mass
m2 = 8.0 ✕ 10−27 kg,
moves in the positive x-direction with speed
v2 = 3.4 ✕ 106 m/s.
Find the magnitude and direction of the velocity of...

1. You shoot a bullet of mass m=0.025 kg into a wood box of mass
M=1.7 kg which initially is at rest. After the impact, the wood
with embedded bullet moves to the flat top of the hill, and it
continues its motion on the top. Initial speed of the bullet before
collision is vo=560 m/s. The height of the hill is h=0.3 m. The
surface has no friction. At what speed the wooden block moves on
the top of...

A 0.14 kg baseball moves horizontally with a speed of 34 m/s
toward a bat. After striking the bat the ball moves vertically
upward with 40% of its initial speed. Find the direction and
magnitude of the impulse delivered to the ball by the bat.

A billiard ball of mass m = 0.25 kg strikes the cushion of a
billiard table at θ1 = 46° and a speed v1 =
25 m/s. It bounces off at an angle of θ2 =
670 and a velocity of v2 = 17 m/s. What is
the magnitude of its change in momentum (in kg·m/s)?

A billiard ball of mass m = 0.25 kg strikes the cushion of a
billiard table at θ θ 1 = 54° and a speed v1 = 22 m/s. It bounces
off at an angle of θ θ 2 = 590 and a velocity of v2 = 15 m/s. What
is the magnitude of its change in momentum (in kg·m/s)?

Suppose a large ship has a momentum of 1.55 × 109
kg⋅m/s.
(A) What is the mass of the large ship, in kilograms, if the
ship is moving at a speed of 45 km/h?
(B) How much larger is the ship’s momentum than the momentum of
a 1025-kg artillery shell fired at a speed of 290 m/s?
A person slaps her leg with her hand, bringing her hand to rest
in 250 ms from an initial speed of 3.95 m/s...

Block 1, of mass m 1 =9.50 kg , moves along a frictionless air
track with speed v 1 =27.0 m/s . It collides with block 2 m2 =13.0
kg , which was initially at restThe blocks stick together after the
collision.
Find the Magnitude p1 of the total inital momentum of the two
block system.
Find vf, the magnitude of the final velocity of the two block
system.

A ball with mass of m=0.5 (Kg) has velocity of V1= 8 m/s and
moves with the angle of 45 degrees with respect to vertical line.
