Q. A 13 g bullet traveling 222 m/s penetrates a 2.0 kg block of wood and emerges cleanly at 162 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges?
Q. The distance to the Andromeda Galaxy is estimated at about 2 x 10(6) light years. A light year is the distance traveled by light in one year; if the speed of light is 3 x 10(8) m/s, about how far is it from our galaxy to Andromeda? (1 year =3.15 x 10(7) s.)
A shell of mass m and speed v explodes into two identical fragments. If the shell was moving horizontally (the positive x direction) with respect to Earth, and one of the fragments is subsequently moving vertically with speed v, find out the velocity..
A standardized biological microscope has an 8.0--focal-length objective. What focal-length eyepiece should be used to achieve a total magnification of.
Assume that when you ride on your 7.60-kg bike the weight of you and the bike is supported equally by the two tires. If the gauge pressure in the tires is 78.5 lb/in2 and the area of contact between each tire and the road is 7.13 cm2, what is your we..
At t = 0 a grinding wheel has an angular velocity of 27.0 rad/s. It has a constant angular acceleration of 32.0 rad/s2 until a circuit breaker trips at t = 2s. From then on, it turns by 432 rad as it coasts to a stop at constant angular accelerati..
what force is needed to pull a 150 pound sled along a horizontal surface? The coeficient of kinetic friction is 0.10 and the sled is pulled by a rope that makes the angle of 0 degree with the horizontal. There is no acceleration.
A helicopter is ascending vertically with a speed of 5.02m/s. At a height of 140m above the Earth, a package is dropped from the window. How much time does it take for the package to reach ground.
On a very muddy football field, a 100 linebacker tackles a 75 halfback. Immediately before the collision, the linebacker is slipping with a velocity of 8.9 north's and the halfback is sliding with a velocity of 7.9 east's.
A spring stiffness 900 N/m and relaxed length 1m stands vertically on a table. You hold a block of mass 1 kg barely touching the top of the spring. Assume you let the mass down onto the spring certain distance very slowly and view the mass is not mov..
Compute an inductance of the sensor for air gaps
The electric field points radially outward at all points within the sphere (and outside too, for that matter). What is the strength of the electric field at a distance r from the center, inside sphere.
A gun is fired vertically into a 2.00 kg block of wood at rest straight above it. If the bullet has a mass of 21.0 g and a speed of 198 m/s, how high would the block rise into the air after the bullet becomes embedded in it.
An electric field of 7.90 x10^5 V/m is desired between two parallel plates, each of area 41 cm2 and separated by 2.45 mm of air. What charge should be on each plate.
