Homework Answers
KE = 0.5mv^2
velocity is the same
so car with higher mass will have higher kinetic energy
so Car B will have larger kinetic energy

Consider a system of two toy rail cars (i.e.. frictionless masses)- Suppose that car 1 has mass 6 kg and is traveling at 3 m/s toward the other car- Suppose car 2 has mass 3 kg and is moving toward the other car at 9 m/s. There is a bumper on the second rail car that engages at the moment the cars hit and does not let go (it connects the two cars). The bumper acts as a spring with...

Two cars moving in the opposite direction have a head-on collision, in which both come to rest. Calculate the average force exerted on car A during this collision. Given: Masses: Car A = 1000 kg Car B = 1200 kg Speeds: Car A = 30.0 mile per hour Car B = 25.0 miles per hour Time of collision = 0.150 s.

Two railroad freight cars with masses 130 Mg and 170 Mg approach with equal speeds of 0.320 m/s . They collide, the lighter car rebounding opposite its original direction at 0.270 m/s . a) Find the velocity of the heavier car after the collision. Assume the original direction of the lighter car is positive. b) What fraction of the original kinetic energy was lost in this inelastic collision? Thanks

Two railroad freight cars with masses 100 Mg and 150 Mg approach with equal speeds of 0.310 m/s. They collide, the lighter car rebounding opposite its original direction at 0.270 m/s . Find the velocity of the heavier car after the collision. Assume the original direction of the lighter car is positive. What fraction of the original kinetic energy was lost in this inelastic collision? Express your answers using two significant figures.

Students perform two experiments using toy cars For each experiment the students measure: the mass* of the toy cars . the amount of force applied to the cars . the speed of the cars after 4 seconds A. Place either Force or the Mass into the box to identify which effect is being tested for each of the two tables B. Place numbers into the blank boxes in the tables to infer the final speed of the car in each...

Two automobiles are involved in a race over level ground. Both cars begin at rest. The Andi accelerates ar 4 for T seconds and then travels at constant velocity for the rest of the race. The Buick accelerates at A/2 for 27 seconds and then travels at constant velocity for the rest of the race.

Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1200 kg and was approaching at 6.00 m/s due south. The second car has a mass of 800 kg and was approaching at 21.0 m/s due west. (a) Calculate the final velocity 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...

Save Answer QUESTION 10 points The given figure shows two blocks A and B of masses 200 and 300kg respectively. The blocks are joined by an inextensible cable. As the system was on rest; a force F-5430 N directed horizontally to the left is applied on block A Use the work and energy principles to determine the velocity of block A after it has moved 0.4m. Assume that the coefficient of kinetic friction between block A and the plane is...
