A RED toy car of mass 4.7 kg, hits BLUE toy car, with mass 1.2 kg, head-on. The blue car originally had a velocity of -15 m/s. After the two cars collide, they stick together and stop. What was the Red car's original velocity?

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

Assume this car is driven off a cliff . how many arrows of force need to be drawn in the free body diagram? assume no air resistance -five -one -three -four
