A 900-kg small car slows down to 20.0 km/h to read a road sign. A 2400-kg passenger van following the small car fails to see that the small car has slowed and continues traveling at 70.0 km/h. The passenger van slams into the small car. Assume both vehicles are traveling in the same positive direction. (i) With what velocity will the two vehicles move if they lock bumpers after the rear-end collision? (ii) Find the change in the kinetic energy of the system consisting of both vehicles.

To increase the acceleration of a rocket, should you throw rocks out of the front window of the rocket or out of the back window?
Three skydivers are plummeting earthward. They are initially holding onto each other, but then push apart. Two skydivers of mass 70 and 80 kg gain horizontal velocities of 1.2 m/s north and 1.4 m/s southeast, respectively. What is the horizontal velocity of the third skydiver, whose mass is 55 kg?

Most of us know intuitively that in a head-on colli-sion between a large dump truck and a subcompact car, you are better off being in the truck than in the car. Whyis this? Many people imagine that the collision forceexerted on the car is much greater than that exerted onthe truck. To substantiate this view, they point out that thecar is crushed, whereas the truck is only dented. This ideaof unequal forces, of course, is false; Newton’s third lawtells us that both objects are acted upon by forces of thesame magnitude. The truck suffers less damage because it is made of stronger metal. But what about the two driv-ers? Do they experience the same forces? To answer this question, suppose that each vehicle is initially moving at 8.00 m/s and that they undergo a perfectly inelastic head-on collision. Each driver has mass 80.0 kg. Including the masses of the drivers, the total masses of the vehicles are 800 kg for the car and 4 000 kg for the truck. If the colli-sion time is 0.120 s, what…

A 2.00 kg ball falls off a 200.00 cm high wall. If the time during the collision is 0.050 seconds, what is the force of impact caused by the (include the unit in your answer - no spaces between number and unit) ground on the ball?
A cat (mass of 3.63 kg) is on a sled (mass of 22.7 kg) which rests on an icy surface... so no friction. In front of this sled, there is another identical sled. The cat jumps from the first sled to the second AND immediately back to the first. Both jumps are made at a relative speed of 3.7 m/sec between the cat and the sled it is on. Calculate the final speeds of the two sleds!
A scooterist moving with a speed of 36km/h sees a child standing in the middle of the road. He applies the brakes and brings the scooter to rest in 5s just in time to save the child. Calculate the average retarding force on the vehicle, if mass of the vehicle and the driver is 300kg.
