A 5g bullet is fired into a 2.995kg block of wood which is the bob of a ballistic pendulum. If the bob leaves its equilibrium position with a speed of 1m/s.
a. Find the speed of the bullet
b. Height above the equilibrium position reached by the center of gravity of the block
The convex lens of a copy machine has a focal length of 25.0 cm. A letter to be copied is placed 40.0 cm from the lens. How far from the lens is the copy paper? The machine was adjusted to give an enlarged copy of the letter. How much larger will the..
What is the final velocity of the space shuttle after a vertical takeoff of 2 minutes with exhaust velocity u= 2900m/s, an initial total mass of 2.04 x 106 kg.
A small glass bead has been charged to + 30{\rm nC}. What is the magnitude of the acceleration of a proton that is 3.0{\rm cm} from the center of the bead
Assume that the acceleration of the ion in the previous problem is 2.8 × 1011 m/s2.
The weight of the block on the table is 484 N and that of the hanging block is 165 N. Ignore all frictional effects, and assuming the pulley to be massless. Find the acceleration of the two blocks
A rainbow trout is an extremely cautious fish constantly monitoring the surface of the stream looking for both food and predators. A trout escapes immediately, once noticing something suspicious, like a fisherman caring his fishing gears.
A pendulum with a length of precisely 1.000 m can be used to measure the acceleration due to gravity g. Such a device is called a gravimeter. How long do 183 oscillations take at sea level
A 5kg mass starts from rest and slides down on an inclined plane, hits a bumper at the bottom of the inclined plane and bounces back up the inclined plane and comes to rest again. During the collision with the bumper, 0.7j of energy is lost. The m..
Over what distance does another astronaut at the radius 215.0m on the outer ring move in the same time? Over what angle, in degrees, did the space station rotate in this period?
Multiple-Concept Example 11 deals with a situation that is similar, but not identical, to that here. What is the mass of the bar
When a potential difference of 188 V is ap- plied to the plates of a parallel-plate capacitor, the plates carry a surface charge density of magnitude 43 nC/cm2. What is the spacing between the plates
A rifle with a barrel length of 59cm fires a 8g bullet with a horizontal speed of 430m/s . The bullet strikes a block of wood and penetrates to a depth of 15cm.
