A block of mass M1 slides with speed vo along a frictionless surface
towards the three masses, M2, M3 and M. which are at rest in the path
of M, as shown in fig
masses are successively smaller, that is,
МA << M3 << M2 << Mi
What is the velocity of mass M4 after the collision? Assume that all
collisions are perfectly elastic. Help: The problem is made easier if each
collision is considered individually.

Two solid iron spheres of masses m and 2m respectively, are suspended from two inextensible ropes of length l. We separate the ball of mass m from its equilibrium position at an angle α, keeping the string extended in the same plane. The mass is released and collides elastically with the sphere of mass 2m. The speed of the sphere sphere of mass m immediately after the collision is:
A puck of mass mA that is moving along the +x axis with speed va collides with another puck of mass mB = 2mA. The collision is not head-on, so that after they collide, mB is located at 45◦ south of east, while mA collides head-on elastically with a stationary puck of mass mC = 3mA. If, after the second collision, the final velocity of mC is 0.450 [m/s], 25◦ north of east, what is the initial speed va?

The figure below is a graph of position versus time for the projectile and target, before and after the collision. (Two line segments are parallel to the time axis.) Which is true about the masses of the projectile and target? 4 O the projectile's mass is greater O the target's mass is greater O the masses are equal
Two objects of masses m1 = 2.0 kg and m2 = 1.3 kg moving towards each other with speeds of 2.2 m/s and 3.1 m/s, respectively, collide inelastically. Calculate the amount of kinetic energy lost in this collision, in joules.
Two masses, m, and m, move on the xy plane towards each other as shown in the figure. The first mass m,=1.1kg is moving with a speed v,=6.7m/s while m,-4.3kg is moving with a speed v,=10.6m/s . As a result of the collision m, comes to rest. What is the final speed of m,? Express your answer using two decimal places. Before the collision
() 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)…

In an Atwoods Machine lab with m1 = 0.1 and m2 = 0.13 observed acceleration is 1.20 m/s^2. Compare the value with the a(theoretical). During the momentum collision lab a 2.5kg mass moving with 2m/s hits a stationary 5kg mass. After the collision 2.5kg bounces back with 0.5m/s and 5kg mass moves with 1.2 m/s. Calculate Pi and Pf and compare using percent error. Does this experiment show conservation of momentum?
