1. A pendulum of mass m=0.225kg and length 45.0cm is held at an angle 28degrees
a) neglecting any air resistance and the mass of the string, how fast is the pendulum going at the bottom of its motion?
b) the pendulum strikes the block (which has mass m=0.650kg) in a perfectly elastic collision. Find the final velocities of the pendulum and the block?
c) the block then slides across the floor a distance of 85.0 cm before coming to rest. What is the average coefficient of friction of the surface?

A pendulum, consisting of a ball of mass m on a light
string of length 1.00 m, is swung back to a 45° angle and released
from rest. The ball swings down and, at its lowest point, collides
with a block of mass 2mthat is on a frictionless
horizontal surface.
Note that you will most likely get different numbers for the
different parts below. As usual, a good way to handle that is to
solve the problem using variables, and...

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...

A steel ball of mass m = 1 kg and a cord of negligible mass and
length L = 2 m make up a simple pendulum that can pivot without
friction about the point O (see below). This pendulum is released
from rest in a horizontal position and when the ball is at its
lowest point it strikes a block of mass m = 1 kg sitting at rest on
a shelf. Assume that the collision is perfectly elastic and...

Problem 3: A bloc of mass m 2.20 Kg slides down a 30.0° incline which is 3.60 m high. At the bottom, it strikes a block of mass M-7.00 Kg which is at rest on a horizontal plane. If the collision is elastic and friction can be ignored, determine: The velocities of the two blocs after the collision, How far back up the incline, the smaller mass will go? 3.6 m M 30°

2. (25 pts.) A simple pendulum of length L = 1.0 m, with a mass mp = 5.0 kg at the end, is held at a 90° angle and released from rest. There are also two blocks, A and B with masses ma = 10 kg and mb = 15 kg, at rest on a horizon- tal, frictionless surface. After the release, the pendulum collides elastically with block A, which in turn collides completely/perfectly inelastically with block B. a. Immediately...

A block of mass m = 2.26 kg slides down an α = 32.8 ° incline
which is h = 3.54 m high. At the bottom, it strikes a block of mass
M = 7.22 kg which is at rest on a horizontal surface, as seen in
figure below. (Assume a smooth transition at the bottom of the
incline.) If the collision is elastic, and friction can be ignored,
determine the speed of the smaller block after the collision.

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 length L = 1.0 meter and bob with mass m = 1.0 kg is released from rest at an angle 0 = 30' from the vertical. When the pendulum reaches the vertical position, the bob strikes a mass M= 3.0 kg that is resting on a frictionless table that has a height h = 0.85m. (a). When the pendulum reaches the vertical position, calculate the speed of the bob just before it strikes the box. (6 marks]...
