Two cars collide at an intersection. Car A, with a mass of 1800 kg , is going from west to east, while car B , of mass 1300 kg , is going from north to south at 16 m/s . As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle...

A 110 kg running back carries the ball south at 8 m/s. A 130 kg linebacker runs to make the tackle going north at 5 m/s. In their collision, the linebacker wraps his arms around the runner and makes it an inelastic collision. How fast are they moving right after the collision (before they fall to the ground)? 3. A 2000 kg SUV traveling at 7 m/s south runs into the rear end of an 800 kg compact car sitting...

Question 8 1 pts The driver of a car wishes to pass a truck that is traveling at a constant speed of 20.0 m/s. Initially, the car is traveling at a speed 25.0 m/s and its front bumper is a distance 24.0 m behind the truck's rear bumper. The car begins accelerating at a constant acceleration 0.6 m/s2, then pulls back into the truck's lane when the rear of the car is a distance 26.0 m ahead of the front...

A. A truck (mass 3274 kg) and a car (1559 kg) collide. The truck moves at a speed of 53 m/s towards the stationary car. Assuming this is an elastic collision, how fast will the bruck be going after the collision? Answer as a whole number. B.A cylinder initially traveling at 3 m/s rolls up a hill inclined at 48 degrees. What is its vertical height when it comes to rest? Give your answer to one decimal place. C. A...

Two cars collide at an intersection. Car A, with a mass of 1900 kg, is going from west to east, while car B, of mass 1500 kg, is going from north to south at 17.0 m\s. As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 60.0degrees south of...

1. A stationary refrigerator car with mass 2.0 x 104 kg is rammed by a loaded gondola car with mass 3.0 x104 kg. Before the impact, the gondola car was going 1.0 m/s. If they lock together, what is the new velocity? 2. A force of 30 N accelerates a 2.0 kg object from rest for a distance of 3.0 m along with a level, frictionless surface; the force then changes to 15 N and acts for an additional 2.0...

A 1 145.0 kg car traveling initially with a speed of 25.000 m/s in an easterly direction crashes into the back of a 9 700.0 kg truck moving in the same direction at 20.000 m/s. The velocity of the car right after the collision is 18.000 m/s to the east. What is the velocity of the truck right after the collision?(I found this) =20.826 (b) What is the change in mechanical energy of the car
