A projectile of mass m, = 2.00kg is fired at an asteroid of mass M = 400kg at a speed of m V =1000- in the direction shown. The asteroid breaks into two pieces, m, =100kg and %3D S m, = 300kg. The final speeds of the asteroid pieces are v, =10.00 and v, = 5.00 in the m m S S directions shown. What are the final speed and direction of the velocity of the projectile after the collision? (Note: The projectile has not been drawn in the "after" picture of the diagram but must be included.) Before After V, 15° m. M m v 35°

A 60 g ball of clay traveling east horizontal at 5.0 m/s collides with a 40.0 g ball of clay traveling 30° south of west at 3.0 m/s. What are the speed and direction of the resulting .0 blob of clay?

You launch a 20 kg shell at 45 degrees and at a speed of 25 m/sec. 1 second after launching it, it explodes into two fragments. Note that the first fragment of 15 kg has a speed of 30 m/sec horizontally forward immediately after the explosion. What is the speed of the second fragment ?

At  t=  0st=  0s  you launch a lump of sticky clay with mass  m1=  13kgm1=  13kg  and velocity  7m/s  i^7m/s  i^  directly toward a block of mass  m2=  31kgm2=  31kg  that is sliding directly toward the clay with a velocity of  −9m/s  i^−9m/s  i^ .  The clay sticks to the block completely.  How much kinetic energy was lost during the collision?

A rock (rock 1) is flying in the sky towards another rock, rock 2. Rock 1 has a mass of 60 kg, and Rock 2 has a mass of 10 kg. Rock 1 is in the sky with a speed of 25 m/s towards Rock 2, and rock 2 is movingtowards Rock 1 in the opposite direction with a speed of 35 m/s. If the two rocks stick together, what is their final velocity? Ignore air resistance and gravity. Is there a change in the kinetic energy of the system? If so, what is it?

A bumper car A (ma = 140 kg) with a velocity of 15 km/h hits a another car B (mb = 160 kg) which was immobile before impact. The collision is perfectly elastic and the frictions are considered negligible. Calculate the time at which the dodgems are 2 m apart from each other after the collision.During a squash game, a player hits the ball, of 24 g, which is moving toward him horizontally at 150 km/h. The impact between the racket and the ball lasts 1.2 ms and the ball leaves with an identical speed but in the opposite direction as the initial velocity. The ball then hits the wall in front, 8 m away and 18 cm below the height of the hit. What is the average force acting on the ball during the impact?

5. A 3000g crate of cakes travelling at 10ms^-1 collides with 15kg box of cans of diet coke travelling in the opposite direction at 5ms^-1 on a frictionless surface. The crates of cakes rebound at 4.5 ms^-1, at what velocity and what direction does the box of cans travel after the collision?

A 11 g bullet is fired into the bob of a ballistic pendulum of mass 1.3 kg. When the bob is at its maximum height, the strings make an angle of 60° with the vertical. The length of the pendulum is 2.3 m. Find the speed of the bullet. m/s еВook

A 8.0kg puck floating on an air table is traveling east at 10cm/s. Coming the other way at 30cm/s is a 2.0kg puck on which is affixed a wad of bubble gum.The two slam head-on into each other and stick together. a) Find their velocity after the impact.b) How much kinetic energy is lost?
