An 2000-kg car stopped at a traffic light struck from the rear by an 800-kg car. The two cars become entangled. moving along the same path as that of the originally moving car.
If the smaller car were moving at 10.0 m/s before the collision, what is the velocity of the entangled cars after the collision?
a. 5.86 m/s
b. 4.86 m/s
c. 2.86 m/s
d. 3.86 m/s

A van, stopped at a traffic light, is hit directly in the rear by another car traveling at 4 m/s. Assume that the transmission of the van is in neutral, the brakes are not being applied, and the collision is elastic. If the mass of the car is 835 kg, and the final velocity of the car is -0.4 m/s, what is the mass of the van kg and what is the final velocity of the van?

A 1055-kg van, stopped at a traffic light, is hit directly in the rear by a 665-kg car traveling with a velocity of +2.35 m/s. Assume that the transmission of the van is in neutral, the brakes are not being applied, and the collision is elastic. What is the final velocity of each vehicle? car m/s van m/s

A 831 kg car stopped at an intersection is rear-ended by a 1830 kg truck moving with a speed of 14.5 m/s. If the car was in neutral and its brakes were off, so that the collision is approximately elastic, find the final speed of both vehicles after the collision. speed of car in m/s speed of truck in m/s

In
the "before" part of the figure, car A (mass 1200 kg) is stopped at
a traffic light when it is rear-ended by car B (mass 1200 kg). Both
cars then slide with locked wheels until the frictional force from
the slick road (with a low μk of 0.16) stops them, at distances dA
= 8.0 m and dB = 5.3 m. What are the speeds of (a) car A and (b)
car B at the start of the sliding,...

A car is stopped at a traffic light. It then travels along a straight road so that its distance from the light is given by x(t)=bt2−ct3, where b = 3.00 m/s2 and c = 0.110 m/s3 . A. Calculate the average velocity of the car for the time interval t = 0 to t = 10.0 s. B. Calculate the instantaneous velocity of the car at t=0. C. Calculate the instantaneous velocity of the car at t = 5.00 s....
