From the SUV-compact car example, suppose the same two vehicles are both traveling eastward, the compact car leading the SUV. The driver of the compact car slams on the brakes suddenly, slowing the vehicle to 6.00 m/s. If the SUV traveling at 18.0 m/s crashes into the compact car, find the speed of the system right after the collision, assuming the two vehicles become entangled, Answer: The speed of the system is ___ m/s.
In a game of curling, a collision occurs between two stones of equal mass. The object stone is initially at rest. After the collision, the stone that is thrown hasa speed of 0.56m/s in some direction, represented by q. The object stone acquires a velocity vf2= 0.42m/s at an angle of f= 30.0o from the original direction of motion of the thrown stone. Determine the initial velocity of the thrown stone.
A small block with mass 0.200 kg is released from rest at the top of a frictionless incline. The block travels a distance 0.508 m down the incline in 2.00 s. The 0.200 kg block is replaced by a 0.400 kg block. If the 0.400 kg block is released from rest at the top of the incline, how far down the incline does it travel in 2.00 s?
A passenger in a moving bus with no windows notices that a ball that has been at rest in the aisle suddenly starts to move toward the rear of the bus. Think of two possible explanations, and devise a way to decide which is correct.
Usually, we do not walk or even stand on a lightweight boat or raft because of the danger of falling into the water. If you have ever stepped off a small boat onto a dock, however, you have probably noticed that the boat moves away from the dock as you step toward the dock or out of the boat. A heavy dog running on a long lightweight raft presents a similar situation. At first, the raft and the dog are at rest with respect to the water (see figure A below) so that vi = 0. The dog then runs on top of the raft at vd = vd with respect to the water (see figure B below). The dog has one sixth the mass of the raft. Find an expression for the velocity of the raft after the dog began running. (Use the following as necessary: vd.) vr =

Two blocks of different metals are sitting on a steel platform as shown. The blocks are connected by a cord running over a frictionless pulley. The aluminum block has mass m1 = 4.60 kg and the copper block has mass m2 = 6.25 kg, and ? = 31.5°. The blocks are released from rest. Will they move? If the blocks move, what is the magnitude of the acceleration (in m/s2) of the two-block system? If the blocks move, what is the magnitude of the tension force (in N) in the cord? If the blocks do not move, what is the sum of the magnitudes of the forces of friction (in N) acting on the blocks?
