If the pendulum,as shown below, is released from the horizontal
position with the length from the pendulums centre of mass to its
axis of rotation being 2.52 m, the velocity of its bob in the
vertical position is
Homework Answers
From the law of conservation of energy, the kinetic energy at the highest point is equal to the potential energy at its mean position.
0.5mv^2 = mgh
v = sqrt (2gh)
= sqrt (2*9.8*2.52) = 7.03 m/s

Conservation of Energy Ranking Task Six pendulums of various
masses m are released from various heights h above a tabletop, as
shown in the figures below. All the pendulums have the same length
and are mounted such that at the vertical position their lowest
points are the height of the tabletop and just do not strike the
tabletop when released. Assume that the size of each bob is
negligible.

A uniform rod of mass M and length L is released from its horizontal position. The rod pivots about a fixed frictionless axis at' onc end and rotates countcrclockwise duc to gravity. It collides and sticks to another rod with same length and mass which is ver- tically at rest.

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]...

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...

NEED ASAP A pendulum is made up of a massless rod of length 1.6 m attached to a 4 kg mass. It’s released from rest when the pendulum is horizontal. When the pendulum is vertical, the mass is moving at 4.8 m/s. a) Taking the gravitational potential energy to be zero at the bottom of the swing, what is the initial total mechanical energy? b) How much energy is lost due to air resistance as the pendulum moves from its...
