[This is a particularly challenging problem, incorporating momentum, conservation of energy, and centripetal force. If you find yourself getting annoyed, just remember that I could have turned the block into a projectile as well :-). Consider it a bonus.] A bullet of mass m = 40 g, moving horizontally with speed v, strikes a clay block of mass M = 1.68 kg that is hanging on a light inextensible string of length L = 0.620. The bullet becomes embedded in...

(This is a particularly challenging problem, incorporating momentum, conservation of energy, and centripetal force. If you find yourself getting annoyed, just remember that I could have turned the block into a projectile as well :-). Consider it a bonus.) A bullet of mass m = 40 g, moving horizontally with speed u, strikes a clay block of mass M = 1.45 kg that is hanging on a light inextensible string of length L = 0.770. The bullet...
A bullet of mass 8 g is fired into a 1.2 kg ballistic pendulum (a block of wood acting as the pendulum bob of a thin metal arm attached to a low friction pivot point) that is initially at rest. The bullet exits the block of wood with a speed of 180 m/s and the wooden block swings from its lowest point to a maximum height of 9.2 cm above that location. Determine the velocity of the bullet before it...
A pendulum bob, with mass 1.60 kg, is held at rest initially in a horizontal position as shown. The string has negligible mass and a length of 1.20 m. The bob is then released from rest. It swings down and collides with a block of mass 2.40 kg initially at rest. Ignore air resistance. a) Use the Principle of Conservation of Mechanical Energy to find the speed of the pendulum bob just before the collision. b) (The bob collides with...
Consider a frictionless track as shown in the figure below. A
block of mass m1 = 5.65
kg is released from A. It makes a
head-on elastic collision at B with a block of
mass m2 = 20.0
kg that is initially at rest. Calculate the maximum
height to which m1 rises after the
collision.Two masses are shown on a frictionless wooden track. The left
part of the track curves downward from left to right, starting from
an almost-vertical slope and then decreasing in...
14) (Conservation of linear momentum) An air cart of mass m=1 kg and speed vo-Im's moves toward second identical air cart that is at rest. When the carts collide, they stick together and move as one a) Using the conservation of linear momentum, calculate the velocity ve when the carts stick together (this is also the velocity of the center of mass after collision). b) Calculate the kinetic energy before and after collision. Is the collision elastic Without any calculation,...
A block of mass m = 3.00 kg starts from the rest and slides down a 30.0∘ incline which is 3.60 m high. At the bottom, it strikes a block of mass M = 6.40 kg which is at rest on a horizontal surface (Figure 1). (Assume a smooth transition at the bottom of the incline.) The collision is elastic, and friction can be ignored. (A) Determine the speed of the block with mass m = 3.00 kg after the...

A pendulum of string length 20 cm and bob mass of 1 kg at its end, starts from rest. The pendulum -on with a block of mass 2 kg, initially at rest. The collision is swings down a quarter of a circle and collides head elastic. Neglect the mass of the string. (a) Find the speed of...
As shown in the figure below, object m1 = 1.60 kg starts at an initial height hij = 0.305 m and speed V1 = 4.00 m/s, swings downward and strikes in an elastic collision) object m2 = 4.55 kg which is initially at rest. 4.00 m/s m2 (a) Determine the speed of m(in m/s) just before the collision. X After you are convinced that energy is conserved as m, swings downward for the collision with me, see if you can...
1) A block of mass m = 0.52 kg is attached to a spring with
force constant 119 N/m is free to move on a frictionless,
horizontal surface as in the figure below. The block is released
from rest after the spring is stretched a distance A = 0.13 m.
(Indicate the direction with the sign of your answer. Assume that
the positive direction is to the right.)
(a) At that instant, find the force on the block. N
