Q1-Assume momentum is conserved in this case.

A cart of mass 0.509kg is moving on a friction balanced track with a speed 0.43m/s. It then collides with another cart of mass 0.546kg that is at rest, and become stuck with it. What is the speed in (m/s) after collision?

Assume momentum is conserved in this case.

Q2-Cart A of mass 0.749kg is moving on a friction balanced track with a speed 0.476m/s. It then collides with cart B of unknown mass which is at rest. After collision, the two carts are stuck together with a speed 0.272m/s. What is the mass of cart B (in unit of kg)?

Q3-Assume momentum is conserved in this case.

Cart A of mass 0.929kg is moving on a friction balanced track with a speed 0.44m/s. It then collides with cart B of mass 0.433kg which is at rest. After collision, cart A's speed slows down to 0.129m/s. What is the speed of cart B in (m/s) after collision?

Q4-

the total momentum (linear momentum) is conserved in any collision, not its _________ energy, but its total energy is conserved. In the ballistic pendulum shown in the conservation of linear momentum lesson, if the mass of a bullet is m1 = 10 g and the mass of the block is 8.0 kg and the height that both reach is 5.0 cm, the initial speed of the bullet is _______ m / s. In the Newton pendulum or Newton's cradle the...

A four-wheel cart of mass M = 95 kg is moving along a horizontal surface with a constant velocity V = 3.5 m/s relative to the ground. A person of mass m1 = 65 kg carrying a backpack of m2 = 8 kg runs and catches up to the cart, and then jumps onto the cart. Just before landing on the cart, the person is moving parallel to the ground and the velocity of the center of mass of the...

1. Show that the Kinetic Energy and the Momentum are conserved in this system. (Remember that momentum is a vector, so you need to show the conservation of the momentum in x and y directions separately.) Data: Before the collision: m1= 1kg v1x =1 m/s v1y=0 m/s m2=1kg v2x=-1m/s v2y=0 m/s After the collision: m1= 1kg v1x =-0.778 m/s v1y=-0.629 m/s m2=1kg v2x= 0.778 m/s v2y=0.629 m/s 2. From the data, calculate the direction(angles) of the final velocities of the...
