Description
Q1: Two cars one with Mass (m1 = 10.0 kg) and 2nd
car (m2 = 7.5 kg) collide and move off as
shown. The car with M1 was initially traveling at 3.5
m/s right and the car with M2 was
initially traveling at a velocity of 2.2 m/s left.
a. What type of collision is depicted here?
b. What was the initial momentum of the right car?
c. What was the initial momentum of the left car?
d. What was the final velocity of the coupled cars?
Q2: look at the Diagram

a) Calculate the velocity of the combined wrecked
cars immediately after the condition.
b) Calculate the kinetic energy of all three objects in
the diagram.
C) Calculate the difference, if any, of the total initial
kinetic energies of the cars
Q3: An apple of mass 0.1kg is thrown at a speed of
100m/s against another apple (mass 0.2 kg, speed
50 m/s), as shown in the figure. After the collision,
the bigger apple moves with an upward velocity as
shown in the figure. The other apple moves
downward at a velocity of 70 m/s and an angle of 27
degrees.
a) Write down the equation of conservation of
momentum along the x-axis
b) Write down the equation of conservation of
momentum along the y-axis
c) Determine the velocity and the angle of the bigger
apple after the collision
