An electron and a 0.0500-kg bullet each have a velocity of
magnitude 510 m/s, accurate to within 0.0100%. Within what lower
limit could we determine the position of each object along the
direction of the velocity? electron mm bullet m
An electron and a 0.0220 kg bullet each have a velocity of
magnitude 490 m/s, accurate to within 0.0100%. Within what lower
limit could we determine the position of each object along the
direction of the velocity? (Give the lower limit for the electron
in mm and that for the bullet in m
(b)
What If? Within what lower limit could we
determine the position of each object along the direction of the
velocity if the electron and the bullet...
A bullet of mass m is fired from the initial ground velocity of
magnitude v0 at elevation angle θ0. (a) Express her momentum
relative to the location of the shot as a function of time. (b) How
fast does the momentum change? (c) Calculate the size vector r × F
directly and compare it with the result of problem (b). Why both
results are identical
A) An electron is to be accelerated from a velocity of 5.00×106
m/s to a velocity of 7.00×106 m/s . Through what potential
difference must the electron pass to accomplish this?
B) Through what potential difference must the electron pass if
it is to be slowed from 7.00×106 m/s to a halt?
A 4.00 g bullet is moving horizontally with a velocity of +355
m/s as shown in figure below. The bullet is approaching two blocks
resting on a horizontal frictionless surface. The bullet passes
completely through the first block (an inelastic collision) and
embeds itself in the second one, as shown in part (b). Note that
both blocks are moving after the collision with the bullet. The
mass of the first block is 1150 g and its velocity is +0.550 m/s...
Problem 11 A hunter fires a 30.00g bullet with a velocity of
+350.00 m/s at a 50.00kg target. Just before impact, the target was
moving toward the hunter with at 10.00 m/s. The bullet then strikes
the target and exits with a velocity of +175.00 m/s.
(b) What is the minimum amount of kinetic energy required to
conserve the momentum of the system?
(g) Find the kinetic energy for the system in the zero momentum
frame before the collision.

A 66.5-kg person throws a 0.0500-kg snowball forward
with a ground speed of 33.5 m/s. A second person, with a mass of
57.5 kg, catches the snowball. Both people are on skates. The first
person is initially moving forward with a speed of 2.35 m/s, and
the second person is initially at rest. What are the velocities of
the two people after the snowball is exchanged? Disregard the
friction between the skates and the ice. (Take the direction the
snowball...
A 5.17-g bullet is moving horizontally with a velocity of +369
m/s, where the sign + indicates that it is moving to the right (see
part a of the drawing). The bullet is approaching two blocks
resting on a horizontal frictionless surface. Air resistance is
negligible. The bullet passes completely through the first block
(an inelastic collision) and embeds itself in the second one, as
indicated in part b. Note that both blocks are moving after the
collision with the...
A 4.80-g bullet is moving horizontally with a velocity of +357
