A block of mass m1 = 14.5 kg slides along a horizontal surface (with friction, μk = 0.37) a distance d = 2.55 m before striking a second block of mass m2 = 8.25 kg. The first block has an initial velocity of v = 9.5 m/s. Assuming that block one stops after it collides with block two, what is block two's velocity after impact in m/s?  How far does block two travel, d2 in meters, before coming to rest after the collision?

The Hulk (200kg of pure angry muscle)collides head-on with a truck (2500kg). If the Hulk was running at 10.0m/s and the truck was moving at 15.0 m/s in the opposite direction, after they stick together, what is their speed (in m/s)? Either the Hulk or the truck needs a negative initial velocity.

an iron ball with a mass of 67.5 kg is traveling with an initial velocity of 20.5 m/s. the ball is hit with a hammer, which remains in contact with the ball for 0.20 sec.  how much force must the hammer hit the ball with to cause it to change directions?

A truck (M = 2500kg) collides with a car (m = 1000kg) at a 4-way intersection. Fortunately nobody gets hurt. Suppose the car is going north at 20m/s ( about 45mph) and the truck is coming from the east at 10m/s ( about 22mph). The car and truck stick together after the %3D collision. (a) Find the speed and direction of the car and truck immediately after the collision. (b) Approximately how much energy went into the deformation of the metal that caused the two vehicles to stick together? (c) What assumptions did you make? The

Calculate the distance traveled by the second cart during the 5.0 s interval after the collision.

2.3. A train car is sitting on a level track when a second car moves in. The second car hits the first, their hitches engage, and they move together. Both cars have equal masses of about 120 000 kg, and the second car initially has a velocity of 1.5 m/s. (a) Draw a diagram that illustrates the situation and include an arrow representing the velocity vector of the second car and a separate arrow representing ĉ, the unit vector for the coordinate system along the tracks. (b) Write vector expressions for both the velocity and momentum of the second car using at least two forms of vector notation that have been covered in class. (c) Just before the collision, what is the velocity of the center of mass of the system that includes both cars? Again, express this as a vector. (d) Just before the collision, what is the total kinetic energy of the system that includes both cars?

Big Boris (90kg) skates backward, 1.0 meter ahead of small skater Sofia (45 kg) , holding her hand as they travel 3.0 "/s . At the 30-second mark, Boris starts pulling Sofia past him, so that by 32.0 s she is 1.0 m ahead of him. During that move, what was Sofia's average velocity, relative to Boris? -0.5 m/s -2.0 m/s +2.0 m/s -1.0 m/s +0.5 m/s +1.0 m/s

An object has a velocity (4.69 m/s)i + (-4.4 m/s)j + (4.73 m/s)k. In a time of 5.5 s its velocity becomes (-2.22 m/s)i + (0.00 m/s)j + (4.73 m/s)k. 1) If the mass of the object is 3.31 kg, what is the magnitude of the net force on the object, in N, during the 5.5 s? Assume the acceleration is constant.

Yesterday you saw in the news that the Giant Asian Murder Hornet has migrated to North America. You didn't think much about it until today when one of those suckers crashed at high speed into the screen door at the back of your house (splat!). The thing hit the door so hard that the door swung shut!We will assume that GAMH had a mass of m = 0.069 kg and was moving with an amazing velocity of v = 9.2 meters/second. The GAMH splatted a distance d = 0.65 meters from the hinge. The door itself can be treated as a rod of mass M = 0.955 kg with a length of L = 1.00 meters rotating about its end.Determine all the following:Write the FORMULA for the moment of inertia of the door without the hornet: I =         kg m2Write the FORMULA for the moment of inertia of the door with the hornet: I =         kg m2Determine the angular momentum of the hornet before it collides with the door Lhornet =  kg m2/sDetermine the angular velocity of the hornet-stained door after the collision ?2 =…

If you have a ball with a mass of 6.00kg, that has an initial velocity of vA=(2.00i + 5.00j)m/s and a final velocity of vB=(-2.00i + 8.00j)m/s, What is the change in velocity in unit vector format?   a. -4.00i + 3.00j   b. -2.83i + 3.61j   c. 4.00i – 3.00j   d. 0.00i + 13.0j
