A 15 g bullet traveling at 485 m/s strikes a 0.9 kg block of wood that is balanced on a table edge 0.7 m above ground. If the bullet buries itself in the block, find the distance D at which the block hits the floor.
What is the speed of the block of clay right after the collision. What impulse does the clay exert on the block.
If a flea can jump straight up to a height of 22.0 , what is its initial speed as it leaves the ground, neglecting air resistance?
What is the magnitude of the force applied throughout this time? What is the direction of the force applied throughout this time?
A toy spacecraft is launched directly upward. When toy reaches its highest point, a spring is released and the toy splits into two parts with masses of .c2 kg and .08 kg.
The speed of the block at the bottom of the track is vA = 13.1 m/s, and block experiences an average frictional force of 7.00 N while sliding up the track.
A microscope with an eyepiece lens of focal length 1.90 cm and an objective lens of focal length 1.15 cm is used to examine a section of the brain of a sacrificed rat. The distance between the lenses of the instrument is 24.0 cm and final image is vi..
An advertisement claims that a particular automobile can "stop on a dime." What net force would actually be necessary to stop an automobile of mass 920kg traveling initially at a speed of 56.0km/h in a distance equal to the diameter of a dime, whi..
In a popular amusement park ride, a rotating cylinder of radius 4.00 m is set in rotation at an angular velocity of 6.00 rad/s. The floor then drops away, leaving the riders suspended against the wall in a vertical position.
Assume the mass of the beam is negligible when compared with the mass of the floodlight. Find out the force FT provided by the cable. The acceleration of gravity is 9.81 m/s2 .
What is the effective spring constant (that is, the ratio of force to change in length) of a copper cable that is 7.0 in diameter and 13 long?
You are setting up two standing string waves. You have a length of uniform piano wire that is 6.0m long and has a mass of 0.150kg . You cut this into two lengths, one of 2.6m and the other of 3.4m , and place each length under tension. What should..
After the interaction, the particles (which can't be distinguished) are observed moving at angles 55.3° and 34.7°, both angles being measured with respect to the original direction of motion. Illustrate what are the final speeds of the particles?..
