A car with mass mc = 1382 kg is traveling west through an intersection at a magnitude of velocity of vc = 15 m/s when a truck of mass mt = 1680 kg traveling south at vt = 8.4m/s fails to yield and collides with the car. The vehicles become stuck together and slide on the asphalt, which has a coefficient of friction of μk = 0.5. How far, in meters, will the vehicles slide after the collision?

A rubber bullet of mass m = 0.025 kg traveling at velocity vo 50 m/s hits 15 kg initially hanging at rest from a massless rope. an iron block of mass M After the collision, the bullet bounced straight back at a speed of v1 35 m/s. M M V1 h The effect of gravity on the bullet alone can be ignored. To what maximum height h will the iron block reach after the collision? (Assume that the rope remains tight during the entire process).

A hockey puck is sliding on a frictionless ice, in an eastward direction. It collides with a second hockey puck, initially stationary, which then goes off in the Northern direction. What direction is the first hockey puck moving after the collision?

The figure below shows a man in a canoe on a lake. The man's mass is 74 kg, and the canoe's is 119 kg. The man and canoe are initially at rest when the man throws a package of mass  m = 15 kg  horizontally to the right with a speed of  vi = 4.6 m/s.  What is the velocity of the canoe after the package is thrown? Neglect any resistance force from the water. (Give the magnitude in m/s, and select the correct direction from the options given.)

The mass of a regulation tennis ball is 57.0 g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30 ms. (This number can also vary, depending on the racket and swing.) We assume a 59.0 g ball and a 26.0 ms contact time in this problem. In the 2011 Davis Cup competition, Ivo Karlovic made one of the fastest recorded serves in history, which was clocked at 156 mi//h (70 m/s). Part A: What impulse did Karlovic exert on the tennis ball in his record serve? Take the +x direction to be along the final direction of motion of the ball. Part B: What average force did Karlovic exert on the tennis ball in his record serve? Part C: If his opponent returned this serve with a speed of 55.0 m/s, what impulse did his opponent exert on the ball, assuming purely horizontal motion? Take the +x direction to be in the direction the ball is traveling before it is hit by the opponent. Part D: If his opponent returned this serve with a speed of 55.0…

Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.70 m/s, and bumper car 2 is traveling 79.1° south of west at 4.25 m/s. They collide and stick together, as the driver of one car reaches out and grabs hold of the other driver. The two bumper cars move off together after the collision, and friction is negligible between the cars and the ground. W-OE Car 2 Car 1 Vii (a) If the masses of bumper cars 1 and 2 are 596 kg and 625 kg respectively, what is the velocity of the bumper cars immediately after the collision? magnitude m/s direction ° east of south (b) What is the kinetic energy lost in the collision?

A puck with mass mA = 2.42 [g] moves eastward with speed VA = 1.73 [m/s]. It then collides with another puck of mass mB = 1.25 [g] and is moving northward with a speed vB = 2.26 [m/s]. After the collision,puck A now moves at 48.00 north of east, while puck B moves at 17.00 south of east. What are the speeds of the two pucks after the collision?

A metal object of mass m = 45.77 g with sharp edges hits a wooden block of mass M = 425.3 g at rest on a horizontal surface. Assume that the coefficient of kinetic friction between the block and the surface μk is 0.43. When the metal object hits the block, it is stuck with the block and both start to slide together with velocity vf. They move together after the collision, and stop after sliding ∆x = 1.95 m. What is the initial velocity vi of the metal object before it hits the block in m/s? Keep three significant figures for the answer.

A toy car having mass m = 1.50 kg collides inelastically with a toy train of mass M = 3.60 kg. Before the collision, the toy train is moving in the positive x-direction with a velocity of Vi = 2.35 m/s and the toy car is also moving in the positive x-direction with a velocity of vi = 4.60 m/s. Immediately after the collision, the toy car is observed moving in the positive x-direction with a velocity of 1.90 m/s.       Determine the change ΔKE in the total kinetic energy. Assume friction and the rotation of the wheels are not important so that they do not affect ΔKE.           ------ joules

a student of mass m1= 64 kg runs towards his skateboard, which has a mass m2= 2.9kg and is d=2.85m ahead of him. he beings at rest and accelerates at a constant rate of a= 0.75m/s^2.  when he reaches the skateboard he jumps on it. what is the velocity of the student and skateboard in meterd per second?
