Consider a projectile (0.1 kg) fired into a ballistic pendulum (0.5 kg, r_cm = 0.3 m), the resulting collision is inelastic (see Figure 2) and the pendulum swings to a maximum angular deflection of 20 degree. Assume r_cm is the same with or without the projectile attached. What is the maximum PE for the pendulum? Determine the maximum KE for the pendulum and use this value to calculate the initial velocity of the projectile-pendulum just after the collision. Apply the...

(8.7.l5)Mass m1 = 4.0 kg is traveling in a straight line at 7.Omls when it strikes m2 = 2.0 kg, which is initially at rest. After the collision, m1?s velocity vector makes a 200 angle with the original direction of motion, and m2?s velocity vector makes a 30 Degree angle with the original direction of motion. (a) Find the speeds of the two masses after the collision. (b) Is this an elastic collision? Do a computation which supports your answer.

A pendulum of a mass mp = 3.60 kg hanging at the bottom end of a massless rod of length ℓ = 0.60 m has a frictionless pivot at its top end. As shown in the above figure, a bullet of mass mb = 0.50 kg, moving with a horizontal velocity vb, impacts the pendulum and becomes embedded. The pendulum then swings to rest at its topmost position converting all of its kinetic energy into potential energy. (a) Use the...

OAL Combine the concepts of conservation of energy and conservation of momentum in inelastic collisions. In figure a, a bullet and a wooden block are shown in two configurations. In the first configuration, the block, labeled m2, hangs vertically from a ceiling. A bullet, labeled m1, approaches the block horizontally from the left. A rightward arrow points from the bullet and is labeled vector v1i. A rightward arrow, shorter than the first, points from the block and is labeled vector...
Projectile Inelastic Collision
A ball of mass, m1 =4kg, is launched from a height, y0,1 =2m, at an angle, Θ1 = 40 degrees, with an initial velocity, v0,1= 14 m/s. At 2/3 of the way through its trajectory, it collides with another, very sticky, ball of mass, m2 =5 kg which was moving at an angle, Θ2 = 180 degrees from the positive x-axis with a velocity, v0,2 = 4m/s. If the two balls collide perfectly inelastically, how long after they collide do...

mass m1 with initial velocity v collides head on with a particle of
mass m2, initially at reat. (a) What fraction of the initial
kinetic energy was lost? (b) View the collision from the center of
mass frame and determine if the kinetic enegy of the colliding
particle remain conserved.

A block of mass m1 = 5.0 kg is released from a height of 5.0 m (point A) down a smooth, curved ramp. It makes an elastc headdon collision with a block of mass m2 = 10 kg that is initally at rest. (a) What is the maximum height reached by m1 afer the collision? (b) Afer the collision, m2 glides smoothly untl it hits a rough patch and eventually comes to a stop. What is the length of 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]...

A small wooden block with mass 0.775 kg is suspended from the lower end of a light cord that is 1.52 m long. The block is initially at rest. A bullet with mass 0.0136 kg is fired at the block with a horizontal velocity of 375 m/s . The bullet strikes the block and becomes embedded in it. After the collision the combined object swings on the end of the cord. The block and bullet rise so that the cord...
