Problem 4: Two blocks are traveling toward each other. The first has a velocity of 5 m/sec and the second a velocity of 9 m/sec. After the collision, the second block is moving with a velocity of 4 m/sec in a direction opposite to its initial velocity. If the mass of the first block is trice (3 times) that of the second, determine the following: - The velocity of the first block after collision; - Whether the collision was elastic...
Two particles approach each other with equal and opposite speed, v . The mass of one particle is m , and the mass of the other particle is n m , where n is just a unitless number. Snapshots of the system before, during, and after the elastic collision are shown. Elasic collision in three stages. Before the collision, a ball of mass m moves to right at speed v and a ball of mass n times m moves to...
Two identical sportscars (having masses m) collide at an intersection. The first is initially travelling due east at speed v, and the second is initially travelling due north at speed 2v. Immediately after the collision, the first car is observed to be skidding in a direction theta_1 = 36.9 degree north of east, with a speed 2v. Determine the velocity (speed and direction) of the second car immediately after the collision.
Two particles approach each other with equal and opposite speed, ? . The mass of one particle is ? , and the mass of the other particle is ?? , where ? is just a unitless number. Snapshots of the system before, during, and after the elastic collision are shown. Elasic collision in three stages. Before the collision, a ball of mass m moves to right at speed v and a ball of mass n times m moves to the...
Two particles approach each other with equal and opposite speed, v. The mass of one particle is m, and the mass of the other particle is nm, where n is just a unitless number. Snapshots of the system before, during, and after the elastic collision are shown. Before Collision After m final After the collision, the first particle moves in the exact opposite direction with speed 0.7500, and the speed of the second particle, Vnmfinal, is unknown. What is the...
Two blocks are 2 m away from each other, the first one has a mass 2 kg and is moving with a velocity 7 m/s to the right and the second one has a mass 10 kg and is moving with velocity 5 m/s to the left. The make a completely inelastic collision. (a) Where is their initial center of mass when they were 2 m away from each other? (b) What is their final velocity after the collision? (c)...
Two carts on an air track are moving toward each other. One has mass 2.0 kg and velocity -0.90 m/s, and the other has mass 3.0 kg but unknown speed. They collide in a totally inelastic collision, and move with velocity +1.2 m/s after the collision. What was the initial speed of the second cart (in m/s)?
A car moving with an initial speed v collides with a second stationary car that is one-half as massive. After the collision the first car moves in the same direction as before with a speed v/3. (a) Find the final speed of the second car. (b) Is this collision elastic or inelastic?
Two billiard balls with identical masses of 1 kg move toward each other. The initial velocity of ball 1 is +30 cm/s and the initial velocity of ball 2 is -20 cm/s. The final velocity of ball 1 is -20 cm/s and the final velocity of ball 2 is +30 cm/s. Assume friction and rotation are unimportant. Show, through conservation of energy, that this was indeed an elastic collision. (Hint: Find the kinetic energy of the system before and after...
Three blocks (1,2,3) of mass 3.00 kg, 2.00 kg, 1.00 kg sit linearly 10.0 cm apart from each other on a frictionless surface. A 25 g bullet is shot at the first block, it travels through the first block, and embeds itself into the second block (without falling over) which then collides into the third block. a. Assuming the final collision is elastic, and the third block has a final velocity of 5.00 m/s, what is the velocity of block...
