Answer #1

(a)
An electron and a 0.0260 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.)

A 190-kg
object and a 490-kg
object are separated by 4.40
m.
(a) Find the magnitude of the net gravitational force exerted by
these objects on a 63.0-kg object placed midway between them.
(N)
(b) At what position (other than an infinitely remote one) can the
63.0-kg object be placed so as to experience a net force of zero
from the other two objects?
(m from the 490 kg mass toward the 190 kg mass)

Given the following:
Velocity of an electron is 2.2 X 106 m/s
Mass of electron is 9.11 X 10-31 kg
We know the position of the electron within 10%
What must the diameter of our electron
orbital be? Show your work.

A bullet is launched with an initial speed of 1245 m/s. The
initial velocity in the y-direction is 515 m/s and the initial
velocity in the x-direction is -1208 m/s. When the bullet reaches
the peak of its trajectory, what is the velocity and the
acceleration in the x-direction and what is the velocity and the
acceleration in the y-direction? Consider up to be positive. Please
include a diagram and an explanation of each step. Do you use the
max...

A pistol fires a 0.0050-kg bullet with a muzzle velocity of
1000.0 m/s. The bullet then strikes a 10.0-kg wooden block resting
on a horizontal frictionless surface and becomes embedded in the
block. The block and bullet then slide across the surface. What was
work done on the block and the impulse delivered to the bullet
during the collision?
a. 250J, 12.5N-s
b. 12J, 12.5N-s
c. 1.2J and -5.0N-s
d. 0.15J, -2.5N-s
e. 38J, 7.5N-s
please show work will rate!!

A soccer ball of mass 0.30 kg is rolling with velocity 0, 0, 3.0
m/s, when you kick it. Your kick delivers an impulse of magnitude
1.6 N · s in the −x direction. The net force on the rolling ball,
due to the air and the grass, is 0.28 N in the direction opposite
to the direction of the ball's momentum. Using a time step of 0.5
s, find the position of the ball at a time 1.5 s...

A soccer ball of mass 0.31 kg is rolling with velocity <0, 0,
2.1> m/s, when you kick it. Your kick delivers an impulse of
magnitude 2.7 N·s in the -x direction. The net force on the rolling
ball, due to the air and the grass, is 0.37 N in the direction
opposite to the direction of the ball's momentum. Using a time step
of 0.5 s, find the position of the ball at a time 1.5 s after you...
