The 1.5 kg ball A is released from rest from
a height. As it
descend hits a solid wall. If the coefficient of restitution is
0.85 determine : rebound height after
the impact and angular velocity for a 30° angle respect the release
position (the horizontal)

A block of mass 800 kg is released from rest 2 m above the top of a 2400-kg pile to drive it into the soil. If the block rebounds to a height of 0.1 m after impact with the pile, calculate the coefficient of restitution.

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...

3. A 10 kg block A is released from rest 2 m above the 5 kg plate P, which can slide freely along the smooth vertical guides BC and DE. The coefficient of restitution between the block and the plate is e 0.75. Determine the veloc 2 ity of the block and the plate just after impact. What is impact? The spring has an unstretched length of 600 m450 mm Ans: A 2.61 m/s, p 7.31 m/s and d 0.32...

1) a)You are asked to find the initial velocity of a steel ball from a spring loaded launcher. You place the launcher on the edge of a table 1.0 meter above the floor and launch the projectile several times horizontally. If you find that the average distance the ball travels is 1.3 meters, what is the initial velocity of the ball? To solve a problem like this, use equations for the y-motion to find the time and then the x-motion...

a. The mass of a golf ball is .046 kg; the mass of a club head is .28 kg; and, the velocity of the club head is 55 m/s before it impacts the ball. If the coefficient of restitution of the ball is .82, how fast is the ball moving after impact? (1pt) Use this formula for part a.: v1 = ((CoR + 1)m2u2 + u1(m1 – CoRm2)) / m1 + m2 Where v = velocity after...

A small spring-loaded launcher is designed to fire steel ball bearings with masses of 0.3 kg . When setting the launcher, you compress the spring a distance of 14 cm . You then fire the launcher straight up and find that the projectiles reach a maximum height of 0.9 m above the point that they leave the launcher. You load another ball bearing, compress the spring a distance of 20 cm , and place it horizontally at the edge of...

An 80.0 kg bungee jumper drops from rest off a bridge that is 200.0 m above a river. As he falls, air resistance is negligible, and the unstretched bungee cord attached to him uncoils. The mass of the bungee cord is negligible. When the jumper is 50.0 m below the bridge, the bungee cord is completely uncoiled and forms a straight line. Below that point, the bungee cord acts as a spring, obeying Hooke's law as it is stretched beyond...

2. (40 points) A soccer ball tester consists of a 15-kg slender rod AB with a 1.1-kg sim- ulated foot located at A and a torsional spring located at pin B. The torsional spring has a spring constant of k 910 N.m/rad and is unstretched when AB is its lowest position. Fig. 2 depicts the simulation. The length of AB is 0.9 m, and you can assume that the foot ban be modcled as a particle, Knowing that the velocity...
