A0.014-kg bullet is fired intoa stationary block of wood of mass of 4.51 kg. The relative speed of the bullet with respect to the wood is zero after collision (The bullet becomes embedded in the block of wood). What is the speed of the bullet-plus-wood combination immediately after collision if the speed of the bullet before collision is 476 m/s? Express yourlanswer in two decimal places and with units of m/s.
A 1425 kg truck driving at 13.0 m/s collides elastically with a stationary 1175 kg car. If the car is traveling 14.25 m/s just after the collision, what is the velocity of the truck immediately after the collision? Assume that this is a perfectly elastic collision. Round your answer to the hundredths place. Final velocity of the truck = m/s
Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1400 kg and was approaching at 5.00 m/s due south. The second car has a mass of 850 kg and was approaching at 16.0 m/s due west. a. Calculate the final velocity (magnitude in m/s and direction in degrees counterclockwise from the west) of the cars. (Note that since both cars have an initial velocity, you cannot use the equations for conservation of momentum along the x-axis and y-axis; instead, you must look for other simplifying aspects.) magnitude m/sdirection ° counterclockwise from west b. How much kinetic energy (in J) is lost in the collision? (This energy goes into deformation of the cars.) J
