l Determine the initial Kinetic Energy for the two masses below 1kg 3kg
A one-dimensional perfectly elastic collision occurs between two masses on a frictionless surface. The initial kinetic energies of the masses were 10 J and 5 J. After the collision the kinetic energy of one of the masses is 20 J. What is the kinetic energy of the other mass?
Three perfectly elastic bodies of masses 5kg. 1kg, 5kg are arranged in that order on a straight line, and are free to move along it. Initially, the middle one is moving with velocity 27m/s. and the others are at rest. Find how many collisions take place in the subsequent motion, and verify that the final value of the kinetic energy is equal to the initial value.
theta is 90 degrees
3. Two boxes with the masses m =3kg and m2 = 10kg are connected by a massless rope over a pulley that is made in the shape of a disk with radius R=15cm and mass M=800g, as shown in the Figure. The coefficient of kinetic friction for the motion of either box on both horizontal and sloped surfaces is 0.12. The boxes are released and allowed to move. (a) Find force of tension between box 2...
Two masses of 4 kg and 16 kg are moving with equal Kinetic energy. What will be the ratio of their momentum? 3:20 1:2 2:9 1:8
two balls that are set to be collide elastically, give these two balls specific masses and initial velocity. The balls cannot have the same mass, and they must be moving in both the x- and y-directions. These are the data: Mass for ball 1=3kg Mass for ball 2=5kg Initial velocity ball 1=1.50 Initial velocity ball 2=2.0 Use Conservation of Momentum in x and y, as well as Conservation of Energy, to determine the final velocities of the balls after the...
Question 24 Two masses of 4 kg and 16 kg are moving with equal Kinetic energy. What will be the ratio of their momentum? 2:9 3:20 1:8 1:2
True and False 1. If two particles of different masses have equal kinetic energy they also have equal momentum. 2. If the momentum of a single particle is zero, its kinetic energy may not be zero. 3. The kinetic energy is always conserved both in elastic collisions and inelastic collisions. 4. A large force always produces a larger impulse on a body than a smaller force. 5. If the kinetic energy of a single particle is zero, its momentum must...
Rotational Kinetic Energy: The L-shaped object shown in the figure consists of three small masses connected by extremely light rods. Assume that the masses shown are accurate to three significant figures. How much work must be done to accelerate the object from rest to an angular speed of 3.25 rad/s (a) about the x-axis, (b) about the y- axis?
V If two particles of different masses have equal kinetic energy they also have equal momentum. The kinetic energy is always conserved both in elastic collisions and inelastic collisions. If the momentum of a single particle is zero, its kinetic energy may not be zero. The linear momentum of an object is proportional to the mass of the object. A large force always produces a larger impulse on a body than a smaller force. If the kinetic energy of a...
