Q(5) In the Linear Momentum experiment; two gliders of equal masses, mi placed on a horizontal frictionless track. Glider mi is given an initial velocity vi to the right, and the glider m2 was initially at rest in the middle of the track. After collision, the two gliders stick together and moving to the right with constant velocity vf. The following table shows the readings of timer 1 and timer 2. ( Note: write results in 3 sig. fig.) m2, are mı=350 m2=350 g, the length of the glider 1 is L1= 10 cm the length of the glider 2 is L2= 10 cm Trial 1 ti (s) 0.122 t2 (s) 0.488 1- Complete the table, what type of collisions that the trial represents.

Quesitos: The drawing shows a bullet passing through two blocks that rest on a horizontal, frictionless surface. Rule out air resistance. The bullet completely passes through the first block and is buried in the second block. Notice that after the collision, both blocks move. Can the Conservation Principle be applied from Linear Momentum to this three-body system? Justify your answer (Ignore any loss of mass from the first block). Problem: A 4.00-g bullet moves horizontally with velocity of + 355m / s. The mass of the first block is 1150 g, and its velocity after the bullet passes through it it is +0.550 m / s. The mass of the second block is 1530 g. (a) Obtain the speed of the bullet after passing through the first block, (b) obtain the velocity of the second block after the bullet is buried in it

Bullets and other missiles fired at Superman simply bounce off his chest. Suppose that a gangster sprays Superman’s chest with bullets of mass m at the rate of n. The speed of each bullet is v and the angle of each bullet with respect to the plane of superman’s chest is θ. Suppose too that the bullets bounce off his chest specularly with no change in speed. Find the average force exerted by the stream of bullets on Superman’s chest. The answer is F=mn2vsin(theta). Can someone explain with steps, how did we get this?

() THE FOLLOWING QUESTIONS ARE BASED ON THE INFORMATION GIVEN BELOW. Block m, of mass 15 kg moving with velocity v = 33 m/s on a frictionless plane collides block mg which is connected to block m3 by a long. massless spring with spring constant k = 7000 N/m: see the figure. Each of blocks mą and mg has a mass of 5 kg. Before the collision, blocks mą and mg are stationary and the spring is relaxed. m2 Frictionless - For parts A. B and Cassume that the collision of blocks m, and ma is completely inelastic. (Because the spring is relaxed before the collision. block mạ does not move at the instant of impact therefore (m, +m2) must move through a finite displacement before any force acts on mg and cause it to move) • For parts D and Eassume that the collision of blocks m, and m, is elastic. (Because the spring is relaxed before the collision. block my does not move at the instant of impact therefore mạ must move through a finite displacement before any force acts on mg and cause it to move)…
