suppose the two cars are headed in the same direction. A 1200kg car travels at 65 mph and a 1000kg car travels at 75mph. The faster car rear-ends the slower car and their bumpers catch so that they continue moving after the collision at the same speed. Use the concepts above ...

Physics
Object A is moving due east, while object B is moving due north. They collide and stick together in a completely inelastic collision. Momentum is conserved. Object A has a mass of mA = 17.0 kg and an initial velocity of VoA = 8.15 m/s, due east. Object B, however, has a mass ...

Physics - Momentum of cars at intersection
Car A(1750kg) traveling due south and car B (1450kg)due east. They reach the same intersection at the same time and collide. The cars lock together and move off at 35.8km/h[E31.6degS]. What was the velocity of each car before the collided? I tried this question using the law ...

Consider two toy cars. Car A starts from rest and speeds up with constant acceleration for a time delta t until it reached a speed of v and then continues to travel at this speed. At the moment car A reaches its maximum speed, car B, starting at rest from the same point that ...

Physics . pls help me :)
Two train cars are on a straight, horizontal track. One car starts at rest and is put in motion with a constant acceleration of 2m/s^2. This car moves towards a second car that is 30 away. The second car is moving away from the first car and is traveling at a constant speed of...

An amusement park ride consists of a car moving in a vertical circle on the end of a rigid boom of negligible mass. The combined weight of the car and riders is 5.0 kN, and the circle’s radius is 10 m. At the top of the circle, what are the (a) magnitude FB and (b) direction (...
