A cart with mass 600 g moving on a frictionless linear air track at an initial speed of 1.5 m/s undergoes an elastic collision with an initially stationary cart of unknown mass. After the collision, the first cart continues in its original direction at 1 m/s.(a) What is the mass of the second cart? (b) What is its speed after impact? (c) What is the speed of the two-cart center of mass?

In the figure, block 1 of mass mi slides from rest along a frictionless ramp from height h = 2.7 m and then collides with stationary block 2, which has mass m2 = 2m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction k is 0.55 and comes to a stop in distance d within that region. What is the value of distanced if the collision is (a) elastic and (b) completely inelastic?

A 44.0-kg boy, riding a 2.80-kg skateboard at a velocity of 5.30 m/s across a level sidewalk, jumps forward to leap over a wall. Just after leaving contact with the board, the boy's velocity relative to the sidewalk is 6.00 m/s, 7.60° above the horizontal. Ignore any friction between the skateboard and the sidewalk. What is the skateboard's velocity relative to the sidewalk at this instant? Be sure to include the correct algebraic sign with your answer. Number i Units Vo V12 The

Two blocks of clay, one of mass 1.00 kg and one of mass 4.00 kg, undergo a completely inelastic collision. Before the collision one of the blocks is at rest and the other block is moving with kinetic energy 32.0 J. (a) If the 4.00 kg block is initially at rest and the 1.00 kg block is moving, what is the initial speed of the 1.00 kg block? What is the common final speed of the two blocks? How much kinetic energy is lost in the collision? (b) If the 1.00 kg block is initially at rest and the 4.00 kg block is moving, what is the initial speed of the 4.00 kg block? What is the common final speed of the two blocks? How much kinetic energy is lost in the collision? (c) In which case is more of the initial kinetic energy lost in a completely inelastic collision: a moving object collides (i) with a heavier object at rest or (ii) with a lighter object at rest?

In the figure, block 1 of mass m₁ slides from rest along a frictionless ramp from height h = 3.3 m and then collides with stationary block 2, which has mass m2 = 3m₁. After the collision, block 2 slides into a region where the coefficient of kinetic friction uk is 0.15 and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic? (a) Number - Frictionless i (b) Number i Unit Unit

A 19.0 kg curling stone is travelling at 3.0 m/s [N] along the smooth ice when it hits an opponent’s stone that is at rest.  (Both stones have the same mass.)  The opponent’s stone rolls off at a velocity of 1.8 m/s [N 22° W]. Determine the percentage of kinetic energy lost during the collision and comment on how close this collision is to being elastic.

A dart of mass m = 10.0 g is fired at and sticks into a block of mass M = 85.0 g that is initially at rest on a rough, horizontal surface. The coefficient of kinetic friction between the block and the surface is 0.400. After the collision, the dart and the block slide a distance of 6.00 m before coming to rest. If the dart were fired horizontally, what would its speed be immediately beforeimpact with the block?

A wood block of mass mw = 200 g is projected from the ground at a speed vn = 35 m/s and at an angle On = 50°. When at height I = 24 m the wood block was hit by a bullet of mass mb = 25 g which was moving at h= 220 m/s and at an angle On = 70°. After the collision, the bullet embedded itself in the block and move together and land at point A on the ground. Then they move on the ground that has coefficient of kinctic friction µa = 0.5 and start to compress a horizontal spring at point B. The distance between point A and B is 18 m and the spring constant k = 3x102 N/m. Right end of the spring is fixed, and all motions are confined in x-y plane. Waod block + Bullet り。 Bullet Wood block (d) Calculate the velocity at which the block-bullet system lands at point A. What will be the speed of it at point B? (e) Determine how much the spring will be compressed when the block-bullet system comes to a rest.
